In regard to your most recent jpeg posting of a diagonal set of black
and white lines, as others have mentioned this appears to be the jaggies
discussed many times before, and I believe it was found to be a timing
problem with the SCSI system, or simply that the scanner and
software/computer couldn't maintain timing somehow.
What I am more interested in is the sharpnness issue. Obviously, the
Nikon scan is sharper, but I was wondering what happens when the image
is manipulated with unsharp masking. I have found that a good scanner
image can use considerable USM with minimal negative fallout. Noisy
scanners suffer with this, but from recent observations I no longer
judge a scanner's quality by looking at the scan prior to unsharp
masking, since most scans require it anyway.
I'd like to see the same two jpeg images made after judicious use of USM
was used by both, just to see if the Nijkon still appears to have the
sharpness benefit it would appear to.
