Hi,
thanks for looking.
Quoting Anthony O'Halloran:

After the tests I have done today, I dont't think so.
I finally atached the scanner to my linux server, the only box with a SCSI
interface in the house.
I used VueScan and there is zero noise in the areas outside the film.
To repeat. I am looking at the slide frame, not the film, when I am talking
about noise. Grain looks similar (depending on how you look at it), but should
happen only on film and not the frame.
So there is noise via the USB interface which is not present when using
SCSI. Unfortunately I need to do at least the initial test scans on
he Mac as there is no real good way of managing color on Linux.
The mac is a PowerBook, so it doesn't have a built in SCSI and I don't
want to shell out the Money for a PCMCIA SCSI adapter if the scanner is broken.
I'll update the web page with a SCSI scanned sample.
