Yes, except that "16 bits" is not 16 different colors but "2 to the power of 16" which is 65536! (see my other reply for more examples) In you above anlogy, you could have a pixel using "24 bits" which would be 8 bits for each basic color Red, Green and Blue. It would mean the scanner can select between 256 different Reds, 256 different Greens and 256 different Blue cans of paint to mix to get the color for that one pixel. (that is over 16 million different colors to choose from) Regards, JvW --------------------------------------------------------- Jan van Wijk; www.fsys.demon.nl - This message is from the Pentax-Discuss Mail List.
