 * A pixel is a contraction of the term **PI**cture **EL**ement
 * Digital images are made up of tiny squares simular to a mosaic
 * Each pixel in the image has a numerical value of between 0 and 255 and is made up of three color channels. So for example a pixel could be 37-red, 76-green and 125-blue
 * There are over 16 million possible combinations using this scheme and each one represents a different color.
 * One of the main ways that manufacturers categorize their digital cameras is in terms of //pixel count//. What this is is the number of individual pixels that go into making each image.
 * Today this number varies between 1 million (//1 Megapixel//) to around 14 million (//14 Megapixels//).
 * A million pixels is abbreviated to MP, so a 1MP camera has 1 million pixels and a 3MP camera has 3 million pixels.
