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.
