The second issue is whether .we have sufficient color resolution(palette width) to accurately display .an individual pixel. Often in the case of flesh tones or solid modeling .we have pixels in adjacent screen positions that are only slightly .differeentiated. In this case palette width is extremely important and .24 bits might not be enough. I hope this has helped explain the roles .of palette width and depth, and why 24bits really has no connection to .display size. Actually, I have seen some amazing pictures in 8 bits. Thses were scanned in photos of peoples faces. They virtually indistingushable from 24 bit pictures. Oddly, or maybe not so oddly, the computer generated images suffered the most from only being displayed in 8 bits. With the right algorithms, you can make an excellent image in eight bits. neil -- Only 3210 shopping days left till the next millenium! Neil F.
