The Polaroid a300 is a digital camera that Polaroid describes as a great digital camera for beginner photographers. The a300 uses an SD memory card to hold the photos you capture. It is PC compatible and you can transfer images directly off of the camera and onto your computer via a USB cable. It features an LED flash, an auto white balance setting, it compresses images into JPEG format and has the ability to capture QVGA video at a rate of 15 frames per second, according to Polaroid.
Megapixels
The a300 camera has a 3.0 megapixel enahnced resolution. The more megapixels a camera has the higher resolution an image will be have in regards to clarity. If the camera has higher pixels it adds more detail into the photograph, which can help in the editing process of images because you have more to work with and image size can be increased or cropped as you see fit. 3.0 megapixels is nearing the low end of resolutions for market digital cameras as of 2010. With the advance in technology newer camera's are being released with between 10 and 12 megapixels. Professional digital cameras can be found with higher resolutions as well.
Zoom
The a300 has a 2x digital zoom. When purchasing a digital camera you should be aware that there are two types of zoom available, some camera's only have one while others might come equipped with both. The first type is digital zoom, the second is optical zoom, which this camera does not have. Optical zoom has ben around since before the invention of digital cameras and is used to get a closer image of a subject. Digital zoom enlarges an area in the photograph digitally. With optical zoom you will not lose any image quality, however with digital zoom you will lose photo quality.
Screen
Digital cameras come equipped with both a viewfinder---like a standard film camera---as well as a digital screen that shows the image you are capturing. The a300 comes equipped with a 1.4 inch bright color Liquid Crystal Display, LCD screen. You will want to experiment with your LCD screen because they have a tendency to make your image appear brighter on the display than it actually is, so if you find your images coming out slightly dark you will want to adjust your brightness settings and keep that in mind when looking at your image from the screen.
