Canon Eos20d Tutorial

Out with film and in with digital! The 20D is a suitable replacement for 35mm Canon film SLRs.


The Canon EOS-20D is a digital single lens reflex camera released in 2005. It features an 8.2-megapixel sensor and an ISO range of 100 to 3200. The APS-C sensor means that images from the 20D have a 1.6x crop factor compared to images taken on a 35mm film body or full-frame digital sensor. The 20D takes standard Canon EF lenses as well as Canon EF-S lenses designed for crop bodies. Using the Canon 20D can be as automated or as involved as you desire, as the camera features a slew of automatic and manual controls.


Instructions


1. Insert the battery and CompactFlash cards into the camera. The battery door is on the bottom of the camera. The CompactFlash slot is on the right side of the camera's face. Install the CompactFlash card with the front label facing you.








2. Attach a lens. A standard kit lens may be an 18-55mm or a 17-85mm lens. To do this, remove the body cap by twisting counter-clockwise. Remove the rear lens cap. Align the white dot on the lens with the white dot on the body (if using an EF-S lens), attach the lens, and twist clockwise until you hear a click.


3. Turn on the camera using the switch on the lower, center part of the camera's face. The camera has two main "On" modes. The first mode is labeled "On," and the second mode is notated with a line. The "On" setting is for all camera functions except exposure compensation. This is useful if you wish to keep the wheel from accidentally changing your exposure values while in any mode but automatic. The "On" mode notated with a line is to enable all features, including exposure compensation.


4. Select your desired image acquisition mode. The simplest mode to use is Automatic, denoted by a green box on the camera's mode dial on the top left of the body. In Automatic mode, all exposure settings are automated, and the flash is deployed automatically if needed. Program (P) mode allows for manual ISO, flash and exposure compensation control, along with control of some lesser features. Aperture priority (A) and shutter priority (T) are used to control aperture and shutter values explicitly. Manual mode (M) is to control aperture and shutter speeds independently of one another.


5. Take a picture using the shutter release, located on the top right side of the camera.


6. Review your images. Press the "Play" button on the face of the camera, which looks like a right-pointing triangle. Use the thumb wheel to scroll through your images.








7. Copy your images to your computer. Use a USB card reader or a USB cable to copy images from your camera to your PC.
