Pixels

Pixel, like salt, means different things. Each letter and every part of any picture that you see on your computer screen is made up of pixels; small uniform sized dots of color. Put many black dots tightly together and you see black. Spread the dots apart with white in between and you see gray. The more closely packed those black dots are, the darker the shade of gray. The more loosely they are packed, the lighter shade of gray.

The printing industry devised many methods for achieving a full range of grays. Initially, none other than William Fox Talbot of the photographic negative fame, proposed a method for using fine screens to break up a photograph into small segments of black ink. It worked, but it wasn’t commercially viable. Eventually, through many trials and errors, a technique evolved for creating patterns of dots that differed in size. The effect is essentially the same as using uniformed pixels of the same size in greater quantities.
