What is 16 megapixels?

Answer 1

This is usually a specification on a digital camera that describes the maximum number of pixels that will be stored in a given image - in this case, 16 million pixels (mega = million). Theoretically, this means that the camera can store more information, so it brings more detail to an image that you take. However, other aspects of Photography go much further towards capturing an accurate image, so don't base a camera purchase on megapixels alone.
