In the picture i attach, you can see a crop. Look at the jagged strange way the pixels ends up along the edge of a face. This is all over the picture. Drumscanned on a ICG365 2600DPI.
Any idea whats going on?
You are using a very high magnification which makes it very difficult to evaluate. I'm not surprised at anything in a scan file when looking at it at 600%. You should see some blurring at the high contrast boundary, and a "boundary layer" of tonal transition.
The curious thing to me is the pattern. That kind of obvious pattern should not occur, even at the 600% level. IOW, I don't see any kind of pattern in my scans from an Optronics ColorGetter 3 Pro drum scanner. Just a guess, but looks like a software problem to me -- the pattern is too large to be hardware or firmware. What does ICG have to say about it?
