What is a digital photo?
DIGITAL PHOTO PIXELS You may have to wait a few seconds for the full sequence of 6 photos to load and play. A digital photo is made up of a series of pixels (picture elements). Most of todays digital photos use a 24 bit RGB system to colour each pixel. This means that each pixel has a 256 colour gradation of red, green and blue. For instance the colour orange is 255 Red, 102 Green and 0 Blue and light pink is 255 Red, 153 Green and 204 Blue. This system can produce 16 million colours which approximates what the human eye can perceive. To confuse things, many modern computers will show a screen colour of 32 bit this is just 24 bit RGB plus an alpha (transparency) channel. Older computers will generally show their highest setting as 24 bit (Truecolor). Either way, to properly view your 24 bit RGB digital images, you should have your computer set to either 24 or 32 bit (whatever highest display setting is offered).
