ABSTRACT
Pixels are the building blocks of video and Photoshop. Think of each pixel as a very small floor tile and Photoshop lays the tile down for you. Each tile can be one of
16.7 million solid colors, in a 24-bit image. These tiles are all the same size and rec-
tangular, and you can see this with a magnifying glass. If the tiles are small enough,
then your eyes will see an image.
