Re: filmscanners: FW: Dual Scan II - striping
Good, I'm glad I haven't fully "lost it" yet ;-)
Two comments.
1) I did some deconstruction of the jpeg image Vlad sent, and the
banding is almost completely in the blue channel... always a weak point
in CCD scanners.
2) The Minolta Dimage Dual Scan II is a USB product, no SCSI interface
card involved.
