Resolution

The resolution of a digital camera is measured in megapixels. Pixels are the image elements in a CCD or CMOS chip. The more pixels, the better the image quality. For most business and home applications you need at least three megapixels. This will allow you to take a picture that is 2048 × 1536 pixels in size and will allow you to reproduce a large 8 × 10 inch image.

Even though a camera is capable of three megapixels, you can take pictures at different resolutions. For example, if your images are only going to be published on the Web, you can use a resolution of 640 × 480 pixels. This will allow you to store more pictures in your computer's memory without having to offload them to your computer.
