Using an amplifier to power speakers inside a home can drastically increase the sound quality of your home stereo. You can also use an amplifier to power your surround sound system to improve your television or movie-viewing experience. Most amplifiers are plug-and-play and simply require a few cables and simple wiring.
Instructions
1. Hook up the audio cable to the amplifier by connecting the output audio cable wires to your amplifier's audio input. Do this by connecting the white output of the cable into the white input of the amplifier and the red output of the cable into the corresponding red input on the amplifier.
2. Connect the other end of the audio cable into the device you'd like to play audio from such as a television or video game console.
3. Connect speakers to the amplifier via speaker wire connections, making sure to match polarities by connecting positive speaker wire outputs to positive amplifier inputs and vice versa for negative polarities.
4. Plug in an amplifier to the designated amplifier plug-in on your amplifier if you opt to use an amplifier in your home stereo. Your amplifier will have an input labeled "subwoofer." You'll also need to plug your amplifier into a wall outlet.
5. Plug the amplifier into a wall outlet. Turn on the amplifier and switch it to the same channel as noted in step one and turn on the audio device.

A super-cardioid microphone offers directional response.
There are two main classes of microphone. Condenser microphones use the interaction of two charged plates to create an electrical current, while dynamic microphones feature a magnet moving within a coil of wire. The term "cardioid" refers to the directional pattern of the microphone.
Direction
"Cardioid" microphones have a heart-shaped response pattern, meaning that they pick up sound directly in front of them--the point of the heart--as well as some sound to the sides--the shoulders of the heart. Super-cardioid microphones have an exaggerated version of the same pattern with greater emphasis on picking up sound directly in front.
Uses
Super-cardioid microphones are sometimes referred to as "shotgun" microphones because of their aptitude for picking up sound accurately at distance when pointed gun-like at the subject. They are useful for recording animal sounds from a safe distance, as well as for picking up one instrument at a time in a band or orchestra.
Drawbacks
Shotgun microphones record little or no background noise, and so can produce isolated, artificial sounding results. It can also be difficult to keep the sound consistent as the subject must remain still within the microphone's narrow area of response.

The Wii is a popular gaming system produced by Nintendo. Continual use, dust and cigarette smoke can build up in the Wii system and cause it to operate poorly. In 2009, Nintendo released a cleaning kit. Regular maintenance with a cleaning kit, including washing off the exterior of the system and the remotes will keep it in top condition.
Instructions
1. Buy a Wii cleaning kit at any electronics store that carries the Wii. Make sure that it has the official Nintendo seal to ensure the kit is approved and recommended by Nintendo. Using a lens cleaning kit from any other type of electronic device is not recommended by Nintendo.
2. Read the step-by-step instruction manual that comes included in the box.
3. Plug your Wii system into the electrical outlet. Press eject to remove a disc that may have been left in the system. Incidentally, you should never leave game discs in the Wii when not in use, because it may cause a strain on the system leading to possible future damage.
4. Apply two to three drops of the cleaning fluid provided in the kit, on the small cleaning pad that is on the cleaning disk. Nintendo directions instruct you not to use more than the recommended drops of solution.
5. Put the cleaning disk into the Wii, holding onto the handle that is on one side. Wait 5 seconds and then move the handle up and down or side to side depending on whether your Wii is in the horizontal or vertical position. Move the handle slowly about 20 times. Let go of the handle and press eject. Remove the cleaning disk. Never pull the disk out without pushing eject first.
6. Clean the Wii system regularly to prevent the build up of contaminates. The Wii cleaning kit is not intended to fix problems, only for maintenance.
7. Send your Wii into Nintendo for maintenance if you are experiencing problems playing Super Smash Brothers Brawl. Nintendo said they will clean the Wii system free in this situation. If your Wii is still not playing or has other problems, check out the Wii website to find out about service options.
8. Clean the exterior of your Wii system when dirt and grime get in the grooves. Use a stiff piece of cardboard the width of a credit card to push through the exterior grooves of the Wii, removing dirt. Spray a clean cloth with a small amount of window cleaner; wipe the exterior of the Wii and the remotes down until they are clean. Do not spray anything directly onto the Wii or the remote. On the back of the Wii, blow the dust out of the screen that covers the fan.

Light flashing stroboscopes are usually too costly for the amateur photographer's budget. One practical and inexpensive way to solve this problem is to build your own mechanical stroboscope. In fact, this stroboscope has advantages over the flashing type, as it can use sun as its light source, enabling the photographer to work with large, outdoor subjects. Read on to learn build a stroboscope.
Instructions
1. Epoxy the step-up ring to a small piece of cardboard that will be the mount of the stroboscope. The cardboard should be large enough that the center of the motor shaft will sit about four inches from the ring. Cut a hole in the cardboard with a box knife to expose the camera lens through the ring. Cut a hole for the viewfinder, if you have covered it as well.
2. Glue the slotted construction paper disc to the center of the motor shaft. Consider buying some sort of flange to make the process of gluing the paper to the small narrow shaft a bit easier. The flange will help protect the delicate paper from the turning motion of the motor shaft.
3. Attach the set-up ring with the motor and slotted disc to the camera lens. Connect the two motor wires to a 9 volt transistor battery. The slotted disc of your stroboscope will immediately begin to turn.
4. Take photos by placing the subject against a dark background, opening the camera shutter where you want the sequence to begin and closing it where you want the sequence to end.
5. Achieve proper exposure with your stroboscope by determining the exposure time delivered by the rotating motion of the slotted disc. Divide the size of the slot in degrees by 360 degrees and multiply the result by the time it takes the disc to make a single revolution. This is the closest estimate of exposure time.

Stanton started manufacturing phonograph components in 1946 with the invention of a replaceable stylus for record players. One of their main products is the phonograph cartridge, which contains the stylus that produces sounds as it moves through the record's grooves.
The Stanton Universal Cartridge series is designed for phonographs with standard or 1/2-inch P-mounts. The P-mount is the mounting hardware that connects the cartridge to the arm.
The L747 cartridge is in the high end of the series.
Stylus Information
The L747 has a Stereohedron stylus type. It's designed to read four-channel stereo tracks, which is how sounds are encoded onto modern records.
The stylus tip (basically, the needle itself), has a radius of .3 mm. It's 2.8 mm long.
It applies between .75 and 1.7 grams in force to the record itself.
Audio Quality
The L747 offers a frequency response (the quality of the sound reproduction) between 10,000 and 25,000 Hz.
It puts out 1.2 megavolts of sound for every centimeter traveled per second. This is the strength of the signal as the record spins on the turntable.
Other Details
The channel balance reflects the balance of sound between left and right speakers in stereo systems. On the L747, the balance is 2 dB.
The L747 weighs six grams. You want to make sure that your cartridge does not weigh more than the phonograph arm can support.
Aerial photos are both breathtaking and useful. Taking photographs from airplanes and helicopters can be a challenging endeavor. However, when done correctly, the aerial photos you take will be will worth the effort.
Instructions
1. Choose to use an airplane or helicopter. Airplanes are sometimes easier to find and rent, but you will often be shooting around a strut or a wing. Planes are also not allowed to fly lower than 1000 feet above congested areas or 500 feet from any person, structure or vessel according to FAA regulations. Helicopters may be harder to find but they can fly lower to the ground, fly slowly or hover. To find an aircraft check the telephone book for local airports or rental facilities.
2. Fly at the right time of day for the best light. The best time to fly is in the early morning or late afternoon. At these "golden hours" the sun is at an angle that provides you with better definition of the objects you are shooting.
3. Decide between a digital or film camera. While in the air you will want to take multiple photos of each object. Digital cameras can have a larger capacity to hold photos and memory cards can be modified and reused on the spot. Film cameras can also be valuable because you can regulate film speed and exposure easily.
4. Reduce vibration and blur in your photos. The factors that influence vibration blur are shutter speed, your ISO setting, aircraft speed and in-camera or in-lens image stabilization. The easiest way to avoid vibration blur is to use a fast shutter speed. On a full-frame camera 1/500th or 1/750th of a second freezes most blur with lenses up to 100mm in length. With a digital SLR, set the exposure mode to "S" for shutter priority or "Tv" for time-value priority and the select 500, 640 or 750. The camera's internal meter will determine a lens aperture for correct exposure.
5. Pick the correct lens and zoom for your aerial photos. Plan to be at least 1000 feet above the subject in an airplane or 300 feet above in a helicopter. Refer to your camera's manual for the best lens and zoom for these distances.
6. Take multiple photographs from different angles. The steeper the angle, the less conventional the photo. The more pictures you take the more choices you have when you get back to the ground. Remember to enjoy your flight and ask the pilot for suggestions on locations.
Display your photos in a way that makes a design statement in your home. Use family photos, decorative frames and shelves to make a wall display. Choose a single large photo to highlight it or create a collage of framed photographs clustered together on one wall. Rotate the way photos are displayed and you'll create a revolving art gallery comprised of family photographs.
Wall Display
Create a wall display featuring a framed photograph. Hang the framed photograph so the middle of the picture is at eye-level. Center the framed photograph so it's either centered on the wall or centered over the main piece of furniture that'll be placed beneath the photograph. Use a wall anchor so the photograph doesn't work loose and fall, damaging the photo and the furniture below it.
Easel
Purchase an easel in the same finish as the frame on the photograph. Position the easel where you want the photo to be and center the framed photograph on the easel. For safety, if there is a hanging wire on the back of the photo, loop it over the top of the easel. The wire helps secure the framed photograph to the easel while it hangs, out of sight, behind the photo.
Shelf
Hang a picture or plate shelf on the wall. Position it so the top of the shelf is where you want the bottom of the framed photograph to be positioned on the wall. Use wall anchors so the shelf stays stable in the wall. Set the framed photograph on top of the shelf. Use a small amount of rubber shelf liner to prevent the photo from sliding around on the shelf. Cut the shelf liner into a very thin strip and set it on the shelf. Stand the frame on top if it. The frame hides the shelf liner from view and the photo won't slide around.
Photo Album
Purchase a high-quality photo album. Choose a decorative photo album and display it on the coffee table. Select an album with acid-free papers so the photos are safe. Select corner protectors and position them on the photograph. Center the photograph on a page in the album and adhere the photo into place with adhesive photo dots. Place several photo dots on the back of the photo and one on each photo corner. Press the photo to the album to secure it. Use photo dots so you can remove the photo without damaging it.

Recording a show from DirecTV entails two distinct steps. First, use the DirecTV DVR (digital video recorder) to select and record the show you want to watch. Once it's stored in the DVR, you can then transfer it to a VHS tape or recordable DVD. (Alternately, you can simply keep it in the DVR for as long as you wish, though transferring it to a disc or tape frees up space on the DVR in order to record more shows).
Instructions
1. Turn on your TV and DirecTV DVR, then press the "Menu" button on the DirecTV remote.
2. Select the "Search for Shows" option on the onscreen list. You can search for a specific show by keyword, by the title of the show or by the channel it's playing on.
3. Highlight the show you want to record and press the "Select" button. You can then decide the conditions under which you wish to record it. You can record an entire series automatically, or just select one swatch, as well as deciding whether you want to keep it permanently or not.
4. Wait for the sair, then double-check the DVR to make sure it has recorded properly.
5. Connect your VCR or DVD recorder to the DVR using a set of RCA cables, component video cables or an HDMI cable. The cables should run from the "TV Out" jack on the back of the DVR to the "Cable In" or "Sat In" jack on the back of the VCR or DVD recorder. Then run a second set of cables from the "Out to TV" jack on the back of the VCR or DVD recorder to the "In From Antenna" jack on the back of your TV.
6. Set the DVR and VCR or DVD recorder to work on the same channel (usually either 3 or 4). Turn on the TV and make sure you're receiving a signal.
7. Place a tape in the VCR or a blank disc in the DVD recorder.
8. Press the "Record" button on the VCR or DVD recorder.
9. Press the "Guide" button on the DVR to call up the list of stored shows, then select the show you wish to record and select. "Play."
10. Allow the splay through, then stop the VCR or DVD recorder when it ends. Rewind the tape (if necessary) and check to make sure the recording was smooth.

Wedding photos are usually taken by professional photographers and high-quality photos are expected to remember the special event.
Ultraviolet or UV filters work with a camera lens to filter out the UV rays that often make pictures taken outdoors hazy or blurry. Filtering out these rays helps keep these photos crisp and easily viewable. Professional photographers will find these filters useful in situations such as outdoor wedding photography where the highest-quality photos are the top priority. These UV filters can help make any setting at any time of day an optimal photo opportunity.
Best in Quality UV Filter

Cameras may seem like fairly complex machines, but they all actually work on a fairly simple principle: capturing light and transforming that light into an image. Although all the bells and whistles make modern cameras fairly sophisticated, all cameras, whether digital or film-based, are composed of the same basic components.
Camera Body
The body of the camera is the casing that you hold in your hands. It houses or acts as a base for the the other components of the camera. The shape and size of the camera depends on what sort of components are inside and how the camera is designed to perform. Single lens reflex, or SLR, cameras tend to be larger than point-and-shoot cameras.
Lens
The lens is the point at which light enters the camera. The lens can be focused to manipulate the light and create a sharper image. The lens reverses the image as it is reflected to the back of the camera. Lenses on SLR cameras can usually be detached from the body of the camera and can be focused manually. Point-and-shoot lenses are embedded in the front of the camera and are focused automatically by a mechanism within the camera.
Aperture
The diaphragm is the part at the back of the lens that controls the amount of light that reaches the film. It works like the iris of an eye. On an SLR camera, the diaphragm changes the aperture, or opening, when you set the f-stops by turning a ring on the exterior of the lens. Point-and-shoot cameras, and auto programs on SLRs, set the aperture automatically.
Shutter
The shutter is the gate that opens to allow light to reach the film of the camera. On an SLR camera, you can set the shutter to open at a specific speed to control the amount of light exposure. Point-and-shoot cameras, and SLR auto programs, set the shutter speed automatically.
Digital Sensor Chip or Film
If your camera is digital, it will contain a digital sensor chip. If it is not, it will be equipped with film. Both of these components serve the same purpose: recording the light that comes into the camera and converting it to an image.
Flash
A flash is important if you intend to take photos in an environment where the natural light is not sufficient to imprint an image on the film or digital sensor chip effectively. The flash will provide a burst of light to illuminate the subject as the shutter opens. Flashes either come built in on a camera or are sold as a separate accessory that fits onto plate on the top of the camera.
Light Meter
A light meter gives you a reading of the amount of light present when you're taking a photograph. This reading helps you to properly set your aperture and shutter speed, or if you're using a point-and-shoot, the light meter controls the automatic settings. Light meters are either built into cameras or come as a separate accessory. In-camera meters only read the reflected light, whereas exterior meters read the true light that is hitting the subject.

It can be hard enough to wire a telephone, electrical or audio line without having to worry about interference. However, modern homes have so many different electrical appliances that shielding is almost always necessary. Here are a few easy ways to shield your wire from interference.
Instructions
1. Use shielded conduit when you're wiring your home to reduce interference. These conduits are more expensive than the non-shielded variety and you should use them only when you must place different kinds near each other. Be sure that you buy flexible conduit if you must use it in corners.
2. Wrap magnetic shielding foil around your wiring to protect it from interference. This material is cheaper than buying shielded conduit, but takes time to wrap around your wiring.
3. Evaluate the cost of wiring your home with shielded wire. Shielded telephone and electrical wires can be purchased from most hardware stores and can significantly reduce interference. However, these wires are more expensive than wire that does not shield against interference.
4. Purchase shielded power cords for home appliances. Some clocks, lights and televisions generate electrical fields even when they're turned off. Using these power cords can reduce interference. However, they are expensive, so you might use them only on appliances that are creating noticeable interference.
5. Keep a distance between different kinds of wires. Electricians recommend that you place telephone, audio and electrical wires no closer than 1 foot from each other. If the wires must be near each other, don't put them in the same conduit.
6. Check the connections to your appliances periodically to be sure that frayed wires aren't causing interference. Some speaker wires fray at the ends, which can cause sounds similar to interference. This problem can be corrected by replacing the wires.

Losing all the data on your iPod can be more than a little frustrating. When it comes to restoring the information, the difficulty is going to vary, depending on if and where you have the files stored as a backup on your computer. The good news is that recovery is going to be possible in most cases, and you can have your information reloaded in a relatively short period of time.
Function
Restoring data to your iPod in some cases will mean recovering the same information that was placed on your iPod at the last sync, if your information was backed up at the same time. However, depending on the program or programs you use for your downloads, you may have to piece back together what you want loaded onto your iPod. Check the settings on your iPod and, if they are not already, restore them to factory settings for the most efficient recovery of files.
Recovery Types
If your iPod files are all or mostly stored in iTunes, a simple sync may be all that is required to recover your data. Most of the time, unless you have set it not to, iTunes will backup the data from the previous sync and store that information for just a time as this. Other download programs may not be so user friendly, and you may have to rebuild your playlists. There are also software programs, which you can find online, designed specifically for the recovery of iPod data. The worst case scenario is that you have to dig into your hard drive and manually retrieve your files. This is time consuming but not difficult.
Considerations
Before attempting any of the recovery procedures, you need to determine if the problem is simply loss of data or if your iPod has a hardware problem. In other words, is it broken? If it is, you need to have it repaired because no type of data recovery is going to solve the problem. If your iPod is in working order, start with the simpler types of recovery, such as syncing to iTunes, and work your way to purchasing a recovery program if necessary.
Prevention/Solution
The best way to avoid the need for data recovery is to make sure your iPod is always kept up to date. Updates for iPod software are released regularly, are free and usually do not take more than a few minutes to install. Keeping your iPod's software current is the most effective way to avoid future data problems. In the event that you do lose your data, having a backup of your last iPod sync will save you a world of aggravation. This is usually available automatically through iTunes or as an option in other programs.
Warning
When it comes to programs that are designed for iPod data recovery, make sure you understand exactly what you are getting. There are numerous programs available that range from free downloads to purchased programs costing over $30. Be careful with the free downloads as they will often have spyware or other undesirable attachments. Purchasing a program from a reputable company is the safest and often the most effective way to retrieve your data.

Depth of field refers to the area of a picture plane between nearest object in focus to the furthest. It is a term most commonly used in photography, but it can be applied to any artistic medium where the feeling of three dimensional space is created on a two dimensional surface by means of "differential focus," or differences in focal points on a single picture plane. Deep depth of field means that most of objects in the picture plane are in sharp focus. Shallow depth of field means that only the primary subject is in sharp focus; all other objects in front of, or behind, the primary subject are out of focus, creating the illusion of three dimensional space.
Instructions
1. Decide how deep or narrow you wish to make the depth of field for your composition. Choose a focal point for your composition. Choose your area of background and foreground and arrange the elements of your composition as you wish them to appear in the final image.
2. Render elements in sharp focus at the focal point of your composition by painting objects with clearly defined details. Use contrast, fine lines and distinct colors to render objects vividly within the area of the focal point. Small, precise brush strokes can create more distinct and coherent elements in an image.
3. Render elements with fewer details in your background, as they recede from the focal point. Use less defined lines, less contrast and more muted colors. Broad brush strokes will create a softer focus, or blurred effect, for your background elements. Use dark, cool colors to create a receding effect for background elements, making these elements appear to be behind the focal point.
4. Render elements with fewer details in your foreground, as they advance from the focal point. Use less defined lines, less contrast and more muted colors. Broader brushstrokes will create a soft focus effect. Lighter, warmer colors create an advancing effect for the elements in the foreground making these elements appear to be in front of the focal point.

A tiny lock-switch is on the left-hand side of the SD card.
SD (Secure Digital) cards are commonly used in cameras, picture frames, music players and other electronic devices. They are solid-state memory, as opposed to a hard drive, which has moving parts. Lexar SD cards can be reliable, however they can sometimes run into problems: they can inadvertently become locked, restricting the addition of further data; they can become corrupted; and they can become full and needing emptying.
Instructions
1. Unlock the Lexar SD card if you are having problems writing to it. Take the card out of the device and, looking at the front of the card, you will see a tiny lock-switch on the left-hand side about three-quarters of the way up the SD card. Move the switch to the down position with your fingernail.
2. Reinsert the card in the device and try to add data. In a camera, this can be done by taking a photograph. Play the data back. In a camera, this could be by viewing the images. If either adding or playing data doesn't work, the card may have become corrupted.
3. Insert the card in another device, say a camera or picture frame, and try to view the images. If you run into problems, the card is corrupted.
4. Salvage the images that you can by copying them onto a computer hard drive or onto the internal memory of the device itself if there's enough space. Reformat the Lexar SD card, preferably in the device you plan to use the card most in. You will lose all the data on the card, but it will likely clear up any problems.

All Canon digital cameras have a built-in USB port, allowing you to import your saved images onto a computer without removing the media card from the camera. Several methods exist to help you increase the connection speed of the USB port so you can upload your images faster.
Instructions
1. Find the USB 2.0 ports on your computer. These ports provide a far faster data transfer speed than older USB 1.1 ports. To determine what ports are USB 2.0, click the "Start" button, followed by "Control Panel" and then "System." In the System window choose the "Hardware" tab followed by "Device Manager." When the Device Manager window opens, scroll through the list until you find the USB listings. The USB ports listed as "Advanced" or "Upgraded" (instead of just USB) are USB 2.0.
2. Plug a USB 2.0 cable into the USB 2.0 port.
3. Insert the other end of the USB cable into the USB port on the camera. With the upgraded cable and USB port, you can now upload images faster from your Canon camera.

High-end speakers have a lot of components and features that contribute to the quality of their sounds. However, these are the reasons they are often expensive. These speakers would still produce sounds if they only had magnets, wire and a source of power. When electricity is applied, the wire generates a magnetic field and the magnet causes the wire to vibrate. This vibration generates audio. Electronics enthusiasts and DIY fans can recreate this process with items found around the house, for under a buck.
Instructions
Make a Speaker with a Styrofoam Cup
1. Connect the wire to the steel brad. Wrap all but 4 inches of each end of the magnet wire near the head of the brass-coated steel brad. You will need the end wire to make a connection to your speaker.
2. Connect the magnet to the steel brad. Stick the magnet just under the head of the brad.
3. Connect the magnet to the Styrofoam cup. Turn the cup upside down. Push the brad through the center of the bottom of the cup.
4. Turn the cup over. Pull the tines of the brad apart and press them against the bottom and sides of the cup. This helps to keep the brad and magnet in place.
5. Clean the ends of the wire. Use the sandpaper to clean about ¾ inches of the end wires. This will remove the enamel coating so that an electrical connection is possible.
Make a Simple Speaker for Your Personal Player
6. Strip the plastic coating off both ends of the wire.
7. Wrap the wire around the magnet. Leave the stripped ends sticking out from the sides of the magnet.
8. Tape the magnet to the center of the paper plate.
9. Cut the wires extending from your headphones. Connect the ends of the headphone wires to the ends of the magnet wire.
10. Test your speaker. Plug the headphone wire jack into your personal player and check for audio.
Make a speaker with a plastic cup and Lego blocks
11. Cut two strips of paper. The paper should be 0.5 inches by 11 inches.
12. Wrap the sides of the magnet with one strip of paper. Place a small strip of tape on the paper to secure it.
13. Wrap the second piece of paper over the first strip of paper. Secure the second strip of paper with a small strip of tape.
14. Remove the magnet from the paper cylinder carefully. Glue the bottoms of the cylinders to the center of the business card.
15. Wait for the glue to dry. When it is completely dry place the magnet back into the paper cylinder.
16. Make a coil. Leaving a long strip of wire at the beginning, wrap about 60 loops of wire around the cylinder. Leave a long strip of wire at the end before you cut the wire. Use a strip of tape to stop the wire from unraveling.
17.Assemble the speaker frame. Leaving enough space in the center of the Lego board for the business card, place a Lego block at each corner. The frame should be approximately 1 inch high.
18. Cover the top of the magnet with hot glue. Avoid putting glue on the paper cylinder.
19. Take the card to the Lego board. Turn it over carefully so that the magnet falls to the top of the paper cylinder and onto the center of the Lego board. Wait for the glue on the magnet to dry so that it is securely attached to the board.
20. Lift the card and the coil off the magnet. Remove the inner paper cylinder from the coil. Leave the second paper cylinder in place, within the coil.
21. Place the card and coil on the magnet. The coil should not touch the magnet.
22. Connect the ends of the wire to each terminal of your plug. Connect one to the ground and the other to the left or right connector.
23. Find out create different speaker designs. Read "Designing, Building, and Testing Your Own Speaker System with Projects" by David B. Weems for more information (see Resources below).

Photo Booth uses a Mac computer camera to take snapshots and video.
Apple's Photo Booth comes included in the Macintosh operating system and allows users to take serious, artistic or humorous pictures using the computer's built in iSight camera or an external digital video camera. In addition to taking standard photos, Photo Booth offers a variety of filters, effects and backdrops. Later versions of Photo Booth also have video capabilities and a quick-shot feature that takes four photos in rapid succession.
Image Filters
Photo Booth's first two sets of effects, image filters and distortion, are part of all Photo Booth versions. The first set of image filters transforms an image's style and coloring in a variety of ways. The effects are normal, sepia, black and white, glow, comic book, color pencil, thermal camera, x-ray and pop art.
Distortion Effects
The second set of effects distorts an image in different ways, often for humorous purposes. These effects are bulge, dent, twirl, squeeze, mirror, tunnel, fish eye and stretch. On certain effects, the user can alter the scope and placement of the distortion.
Backgrounds/Backdrops
Later versions of Photo Booth, beginning with Mac OS X v10.5 Leopard, include additional effects using green screen technology. The subject steps out of the frame, allowing Photo Booth to detect the background, and upon return, the subject is projected in front of a chosen backdrop or movie clip. Photo Booth image backdrops include clouds, color dots and earthrise. Its video clip backdrops are the Eiffel Tower, a roller coaster, a sunset and Yosemite. In addition, users may upload their own photos to use as a backdrop. The green screen technology works best when the user stands in front of a simple background of a bright color, like with a real green screen.

Enlarging digital photos is simple, as long as you keep a few rules in mind.
Although purists will always argue for the superior quality of film cameras, you cannot dispute the conveniences digital cameras and digital photos bestow upon those who use them. Among these is the ability to manipulate and enhance photos quickly, sometimes at the touch of a single button. If you need to enlarge a digital photo, you'll be happy to know that the process is simple, straightforward and will require just minutes of your time to complete.
Instructions
1. Open your photo using the photo enlarger of your choice. If you don't have a special program, you can perform basic enlargements using "Paint" in either Microsoft or Windows, although these may result in lower quality than would be the case using professional software.
2. Access the program's "Resize" feature. In "Paint," you'll find it under the "Attributes" section of the "Image" menu. In online drawing tools such as "OpenOffice.org: Draw", "Pixlr" or "SumoPaint," you will find dedicated entries in the "Image" menu for "Image Size".
3. Enter the dimensions you would like your new photo to be, making sure to click the box next to "Keep Proportions" if you want your photo to appear as a larger version of its current self. In most cases, you will need to enter these dimensions in "pixels." If you are not familiar with pixels, think of the size you want in terms of scale rather than a number. For example, if your photo's length is 500 pixels and you want it to be three times as big, simply enter "1500" into the "Length" box. Click "OK."
4. Inspect your enlarged photo to make sure it meets your specifications. If it doesn't, undo your enlargement by holding down the "Ctrl" ("Command" if using a Mac) and "Z" keys at the same time. Then, re-enlarge the photo to your new specifications.

The activities that take place on the sun have a major impact upon high-frequency (HF) radio broadcasts. Some types of radio propagation affected by the sun's activity include short-wave, AM and ham-radio operations.
Propagating, informing and entertaining
Function
The sun is the source of radiation that affects the state of the earth's ionosphere, which either serves as a reflector of certain types of radio waves (facilitating long-distance communication on Earth) or allows signals above 30 Megahertz (MHz) to pass into space (enabling ground-to-space communication).
Solar Flares
Solar flares emit large amounts of energy and protons, which make their way to the earth. These may have either beneficial or adverse effects upon radio broadcasts depending upon the circumstances.
Coronal mass ejections
Bubbles of gas threaded with magnetic lines that are cast out from the sun are called coronal mass ejections (CME). These may cause short-lived benefits to ionospheric radio broadcasts but can suddenly create blackout conditions.
The Sun's Corona
At times, dark areas appear on the sun's corona (a type of "atmosphere" surrounding the sun) that are associated with open magnetic field lines. These coronal holes create high-speed solar winds that affect ionospheric radio conditions.
Identification
International radio broadcasters, such as Radio Netherlands Worldwide, suggest that radio operators listen to Geophysical Alert Broadcasts, which outline the solar-terrestrial conditions at any given time. (See Reference 3.)

The invention of the DVR has allowed busy people to record their favorite television programs and movies to watch at a later time. This process has been limited, however, to watching these programs at home, on a television set. Many times, it is desirable to be able to watch these programs on the go. Transferring the DVR files to a desktop computer allows the user to watch his shows from the office.
Instructions
1. Open the DVR software application on your computer. Most DVRs have computer applications that allow for easy programming. It is this software that will also allow for the transfer of recorded shows to your PC.
2. Choose the "transfer" option. The DVR application will have an option to transfer recordings to PC and choosing this option will open the menu of available recordings to transfer. Note that not all recordings will be available for transfer based on copyright restrictions.
3. Choose the titles you want to transfer. This process differs from application to application, but most involve either clicking on the boxes beside the title or highlighting.
4. Click on "transfer." The name for this process may differ from one application to another, but the idea is the same.
5. Set up auto transfers. Some DVR applications will allow for automatic transfers of previously selected titles to your PC. This is usually in connection with shows that are a part of a series. Those shows that have this option available will indicate eligibility by enabling the auto transfer option.

We all want to be able to take memorable photos of our family and friends like the one pictured. However, when we are at family events everyone tends to pose for pictures whether you want them to or not. Moreover, since people know you are a photographer they are conscious of your presence and watch you carefully when they see the camera in your hands, so they will not look bad when you take their picture. There is a lot of sneakiness and psychology involved in photography-and in this article I will show you hone your skills with street photography and candid portraits of strangers-to prepare yourself for taking candid portraits at your next family event.
Instructions
1. Get your camera, get out in the street and take pictures of people. Don't ask to take their picture, which will cause them to pose. Just take pictures of people to hone your skills. Don't be confrontational unless you feel the need. Start with simple, non-threatening situations like the one pictured. Become a student of human behavior. When do people notice you? How do you trigger them to notice you? Use a telephoto lens so you can study your subjects from a distance.
2. As you become comfortable taking pictures of people, begin to immerse yourself in your subject. There are a lot of people who like to have their picture taken. Find people who are doing something and photograph them doing it. This is an old picture of a guy in Pittsburgh we used to call the "Birdman of Station Square." He was so involved with his pigeons, he could care less about having his picture taken.
3. Candid portraits usually tell a story or set a mood. As you become more comfortable you can become more confrontational. The more experience you have the faster you become at composition and exposure. This picture was taken within 2 seconds. As I raised my camera to focus, he flashed the peace sign. His glare changed to a shout as I clicked the shutter.
4. Use the telephoto lens to your advantage. This enables you to take pictures from farther away. This picture was taken with a 200mm lens and I was far enough away from my friend to not disturb her contemplative mood. You know you have taken a good candid when you show it to the subject and she says, "oh, when did you take that?"
5. After you have practiced on friends and strangers, you are ready to start taking family candid photographs. Start with someone who feels totally relaxed with you. This is a picture of my wife early in my career. I pointed the camera at her and she swung the tripod up to her eye like a rifle. A completely candid moment made possible by total trust.
6. After you have done all of the above steps, you are probably ready to take pictures of your children. Take advantage of their young years when they totally trust you and the camera. After you take some embarrassing photos, those days will be gone forever. These candid actions and expressions of youth will disappear as they get older and more self-conscious (most will totally hate the camera and having their picture taken by the time they are 10). Enjoy it while you can.

With so many rumors out about Xbox 360 consoles damaging their games, people are looking for ways to save those games to a hard drive. Finally, there is a software program that will let you copy the games directly to the Xbox hard drive. You can also copy them to a separate drive, but it's much harder and riskier.
Instructions
Copying to the Xbox Hard Drive
1. Download the "DVD2XBOX" software onto your Xbox 360 console. Once it's installed, it should appear in the Xbox dashboard under "Applications."
2. Open the DVD2Xbox program and place a game disk in the console. First, go to "Settings" by pressing the white controller button. Enable both the F and G drives. Then, push the back button.
3. Press the controller's "A button" once you have a "DVD: XBOX Software" message at the screen bottom. Choose either the E, F or G drives and the "games" subdirectory to copy the game to. Then, press "A."
4. Start the copying process by pressing the "Start" button. When the machine finishes copying, you will get a confirmation screen and can then exit the program.
Copying to a Separate Hard Drive
5. Connect your console to your PC with an ethernet cable. Create an FTP window on the PC and copy the games onto the computer using the FTP.
6. Convert your copied games into ISO files. You'll need software like ISO or Qwik to do this, and either software type is downloadable for free.
7. Burn the ISO files onto a DVD-R, DVD-RW or CD-RW to make a backup copy of the game disc. You will need DVD burning software that will make Xbox compatible discs. Nero's Burning ROM or Alcohol 120 will do this.

Proper lighting in a digital studio cannot be done without the best floodlights.
Taking photographs and video under poor lighting conditions is tricky at best and can obscure subjects or cause them to look unflattering. Quality digital studio floodlights or continuous lighting kits can help --- and let aspiring photographers and videographers create stunning photos and amazing videos.
Photoflex First Studio Portrait Kit
For people starting out with photography and video, the Photoflex First Studio Portrait Kit can suit beginning needs. The kit includes two 250-watt halogen light bulbs, lamp fixtures, light stands and two umbrella diffusers. Given the contents of the kit, it is basic and is really designed for beginners or for photographers needing an budget-friendly lighting upgrade. The kit, as of 2011, has an MSRP of $249, although its street price can be lower.
Arri 571985 300/650 Fresnel Combo Kit
The Arri 571985 300/650 Fresnel Combo Kit is a continuous lighting system that is easy to set up and use. The kit contains four halogen lamps (two 300-watt and two 600-watt) and accompanying hardware such as scrims, C-47 clothespins for attaching diffusion material, multi-input extension cord and leather gloves for handling the halogen lamps themselves, all of which can be packed a way in a heavy-duty equipment case. The MSRP for this kit (as of 2011) is $3,425, so it is one of the more expensive lighting kits on the market.
ePhoto 2000 and 2275 Watt Digital Photography Studio Video Light Kits
An alternative to halogen-based kits are compact fluorescent lamp (CFL) lighting kits, including the ePhoto 2000 and 2275 Watt Digital Photography Studio Video light kits. Each lamp fixture found in the kits can hold up to five CFLs arranged in a stellate fashion (one lamp pointing dead center surrounded by four others pointing in four directions) and have switches for each lamp instead of the dimmer switch found in halogen lamp kits. The ceramic lamp holders are fixed onto lamp heads made out of plastic and are mounted on lamp stands. The 2000 variant comes with two lamp heads and costs, as of 2011, about $149.99, and the 2275 variant (about $294.99) has two lamp heads plus an additional lamp head with boom stand.
Redhead Continuous Lighting Kits
Redhead continuous lighting kits are powerful kits for the budget-conscious photographer or videographer. Redhead kits come in a variety of configurations from two-lamp (1,600 watts) sets costing, as of 2011, around $75 to four-lamp (3,200 watts) sets that cost around $410. The kits contain rudimentary components such as halogen bulbs, lamps with dimmer switches, barn doors and stands. Users can adjust the focus of the lamps themselves courtesy of a screw at the bottom of the lamp. The most expensive kits from Redhead, the HD Redhead kit, cost only $895 and come with three 650-watt AC heads, barn doors, folding light stands, safety screens and a custom hard case.

Combining the viewing capabilities of binoculars with the picture-taking abilities of cameras makes a great idea. Digital camera binoculars may not be capable of the best image quality, but they're fun gadgets to play with in the outdoors and at sporting events. Plus it's so much easier to carry one camera item instead of two.
Instructions
1. Look at the photo and video taking capabilities of the different models. Most cameras take at least 30-second video clips. Faster video usually means smoother video. Consider buying digital camerabinoculars with an instant replay feature that allows you to look through the binoculars and save up to the 60 seconds of video.
2. Investigate the optics. Camera binoculars are designed to use for distant objects. Binoculars magnification can range from 7X to 10X, but camera optics operate independently of the binoculars. While binoculars may focus up to 15 feet away, the camera may only focus 50 feet away and give you blurry pictures. One maker currently offers a model where the camera and binoculars focus together, the Bushnell Instant Replay 8x32.
3. Check the picture quality. Most camera binoculars range from 3.2 to 5 megapixel cameras. Go for optical zoom over digital zoom for improved picture quality. Find out how your camera performs in different lighting situations.
4. Find out about the lenses of the binoculars. The best use Bak-4 prism glass with fully multicoated lenses. The coatings minimize loss of light and color distortion.
5. Ask about the battery life of your digital camera binoculars. Most models use AA or AAA batteries, which might last an hour of continuous use depending on how often you use the LCD screen. Lithium batteries tend to last longer. Even so, consider camera binoculars with card slots to expand the memory.
6. Check the weight. Digital camera binoculars weigh more than traditional binoculars because of the additional camera lens. Weight differences between models exist as well. Consider how much time you'll be looking through the binoculars, and you can see why weight is a concern. Models with a tripod adapter make this a moot point and limit camera shake.
7. Compare prices. Digital camera binoculars feature a wide range of prices. And while it's true that you get what you pay for, consider what features are most important to you. Make certain a good warranty is included.

Different electronic devices are built to run at different voltages and types of current. In the United States, the the voltage of typical wall outlets is 120 volts, also called mains voltage, and it provides an alternating current, which means that the flow of electricity regularly switches direction. Some power sources, however, most notably car batteries, run on a 12-volt direct current. There are times when you may want to run a device built for a mains voltage from a 12-volt power source or the other way around. In order to do this, you need either a power converter or a power inverter.
Instructions
Setting up a power inverter.
1. Plug the cord from the power inverter into your car cigarette lighter. Because the most common source of 12-volt DC is a car battery, most power inverters are set up to draw power from a standard car cigarette lighter. If you are using a different type of low-voltage power source, follow the directions that came with your inverter unit. In most cases, you will need to connect cables to the positive and negative leads of your power source.
2. Plug your 120-volt AC appliance into the 120-volt outlet plug on the power inverter. Most power inverters have a plug shaped just like a normal wall outlet.
3. Turn on your device and use it normally. Many power inverters have an indicator light that shows that they are working properly. Check that this light is on. Keep in mind that you may need to switch the device on before it begins to provide power.
Setting up a power convertor.
4. Plug the normal-looking electrical cord from your power converter into a 120-volt wall outlet.
5. Connect the cables from your device to the positive and negative leads on the front of your power converter. There should be two places on the power converter to connect the cables--one marked as positive and one marked as negative, and usually colored black and red. Make sure that you connect the positive lead on the converter to the positive cable from your device. Getting the positive and negative cables mixed up could cause your device to not work or even damage it.
6. Switch your power converter on. Electricity should now be flowing, and your device should work normally.

Select the appropriate audio source to hear audio from each device.
When you set up your Philips speakers and wire your TV and audio/video sources to the main unit, you might experience some obstacles with proper sound distribution and functionality. Following a few steps and performing the necessary maintenance yourself will have your sound system set up perfectly before your family and friends arrive to watch the big game.
Instructions
Nonfunctional Buttons
1. Turn the main unit around so that the back is easily accessible to begin correcting a system that isn't working.
2. Examine the power cord from the main unit going to the wall outlet for damage. If the power cord is cut or dented, replace it.
3. Unplug the power cord from the wall outlet and wait for a few seconds to reset the connection. While you're waiting, plug in an alternate electrical device to test the wall outlet for proper functionality. Plug the power cord into the wall.
No Sound
4. Unplug all of your speaker connections from the main unit to reset the connection, if one or all of your speakers fail to emit sound. Each speaker wire is tipped with a color-coding.
5. Plug each speaker wire firmly into its correct color-coded receptor within the "Speaker" section (located on the back of the main unit). The red "Front Right" speaker wire plugs into the red "Front Right" jack; the white "Front Left" speaker wire plugs into the white "Front Left" jack; the green "Front Center" speaker wire plugs into the green "Front Center" jack; the gray "Rear Right" speaker wire plugs into the gray "Rear Right" jack; the blue "Rear Left" speaker wire plugs into the blue "Rear Left" jack; and the purple "Subwoofer" speaker wire plugs into the purple "Subwoofer" jack.
6. Push the "Source" button (located on the front of the main unit) to highlight the proper system that you're engaging. If you're unable to receive audio from your DVD player, push the "Source" button until "Aux 2" is displayed on the screen.
DVD Sound
7. Pull the audio/video component cables out from the main unit jacks and the DVD player jacks.
8. Plug the yellow-tipped video cable into the "Video Out" jack on the back of the main unit. Plug the opposite end of the cable into the "Video In" jack on the DVD player.
9. Plug the white- and red-tipped audio cables into the white and red "Aux 2 Audio In" jacks, respectively. Plug the opposite white- and red-tipped audio cables into the DVD player's white and red "Audio Out" jacks, respectively. Confirm that the colors on the three cables and the jacks are matched.

A wide angle lens is a camera lens with a wider angle of view and a shorter focal length than a lens used to produce a normal image size by that camera.
Function
A wide angle lens allows a photographer to keep an image sharp from a few feet away. It can extend an image's periphery, making it ideal for photographing a tight indoor space or a large group of people. It's also great for shooting landscapes with large sections of the sky and the ground.
Features
The key feature of a wide angle lens is a short focal length, or the measure of how strongly it focuses light. This gives an image a large depth of field, with the foreground and the background in focus at the same time.
Types
Depending on size, lenses are classified as wide angle lenses, super wide angle lenses and fisheye lenses. Fisheye lenses have angles of view ranging up to 180 degrees, producing images that look curved or as if they were captured in a bubble.
Size
For the 35 mm format, a standard wide angle lens is 28 or 24 mm. A super wide angle lens ranges from 20 to 14 mm. A fisheye lens is about 6 to 8 mm.
Considerations
Because of their wide view, wide angle lenses throw off perspective. They're not good for shooting realistic close-ups or portraits because they can magnify and distort items at the edge of the image.
The best 10MP digital cameras have high-end features.
Size doesn't always matter when it comes to megapixels. Although digital camera manufacturers now offer models with 12, 15, and 18 megapixels, today's 10 megapixel (MP) cameras provide excellent resolution to satisfy beginners, advanced amateurs and professional photographers alike. The best 10MP digital cameras have high-end features, such as high-sensitivity image sensors, optical image stabilization, high ISO settings low "noise," fast f/2.8 or wider aperture lenses for low-light shooting, the ability to shoot in RAW, minimal shutter lag, and high definition (HD) video.
Canon Digital Rebel XS
This latest model of Canon's popular Rebel line features a high-sensitivity 10.5 image sensor and captures images in both RAW and JPEG formats. It also boasts high ISO noise reduction technology that was previously available only in Canon's more expensive professional digital SLRs. That means that images captured at even 1600 ISO will have less graininess and sharper detail. The Digital Rebel XS also helps even beginners take perfectly exposed shots thanks to Canon's Auto Lighting Optimizer technology designed to automatically correct image brightness and contrast in backlit scenes. Avanced amateurs and professionals appreciate the Digital Rebel XS for its minimal shutter lag and an exceptionally fast 3 frames-per-second (fps) continuous shooting mode.
Nikon D-3000
The Nikon D3000 is an advanced DSLR that pleases professionals with its fast 3fps burst mode and split-second shutter response. But Nikon also designed the D3000 to make it easy enough for beginners and advanced amateurs to use. The camera's "Guide Mode" and "Scenes Mode" with clearly identifiable icons make it easy to change shooting modes and camera options. This DSLR also features high ISO noise-reduction technology for shooting up to 1600 ISO.
Canon G12
Professional photographers say it's like putting a DSLR in their pocket. The Canon G12 is a powerhouse 10MP point-and-shoot camera with Canon's advanced DIGIC 4 Image Processor, which is the same processor used in some of Canon's professional DSLRs. It shoots in RAW and JPEG, and features a fast, wide-aperture F/2.8 lens to enable low-light indoor shots without using flash. The G12 also excels at low-noise ISO sensitivity up to 3200 ISO for low-light indoor shots, such as in museums where flash is not allowed. Beginners and professionals alike can benefit from the Canon G12's new Optical Hybrid Image Stabilization (IS) system, which helps reduce the effects of camera shake, especially when using the zoom function at its full range. Plus, in addition to performing like its larger DSLR relatives, the Canon G12 also takes HD video with stereo sound.
Fujifilm HS10
This is the 10MP camera to take on your next vacation to the Grand Canyon, or anywhere you want to take panoramic photos. The Fujifilm HS10 features all of the bells and whistles you'd expect from an advanced point-and-shoot, plus the ability to take panoramic shots "in camera." That means that the camera stitches multiple photos together automatically as you sweep the camera across the view you want to capture. The Fujifilm HS10 is also an excellent choice for wildlife photography with its 30x wide-angle optical IS zoom, which is equivalent to a 24-720mm zoom range in a 35mm film lens. The camera also boasts HD video and stereo sound.
Leica D-LUX 5
A very fast, image-stabilized f/2.0-3.3 aperture lens makes the Leica D-LUX 5 the perfect 10MP camera for "available light" no-flash photography, whether indoors or outdoors during early morning or at dusk. It also offers low-noise, high ISO sensitivity up to 12800 ISO, which exceeds the range of even some professional DSLRs. The camera also boasts a 1/1.63" CCD image sensor, which is larger than usual for a 10MP point-and-shoot. As a result, the D-LUX 5 produces a higher level of image quality in terms of contrast and natural color rendition. Although the Leica name has been associated with professional photography for generations, thie D-LUX 5 is simple enough for beginners to use, with its intuitive settings and controls. For the ultimate in creative imagery, this classically designed Leica also features 720p HD video.
