At the beginning of the age of digital cameras, it was all about the number of megapixels. A 2-megapixel camera was better than a 1-megapixel camera and a 3-megapixel camera was better than a 2-megapixel camera. If you wanted a better digital camera, you simply purchased the one with the highest megapixel count. This method of determining the quality of a digital camera became ingrained in the minds of consumers and has been sustained by the camera manufacturers.
