Ben, . . "increasing the bits in the color space has very similar effects to increasing the bits in the spacial resolution." And how! It is amazing how much better (some) VGA images of 320 x 200 look compared to HAM of the same resolution. I have assumed that the smooth transitions in the colors of the VGA were the reason. Although the VGA can display only 256 colors compared to 4096, it can draw from a huge palette and therefore render the image without the 'posterizing' effect seen in Amiga HAM. I have seen some of these low resolution VGA images and at first thought they were of 'photographic' quality. They were probably selected for the potential to display well, but that does not diminish their effectiveness. Increasing the actual resolution is of course an improvement, but the smooth transition of the 'gray scale' factor makes an amazing difference. I can't wait to see a HAM-E image, and would really like to see the higher resolution version. Rich
