Microtek Artixscan F1:
Most often, when I scan tranparencies, I get better scanningresults (sharper, more colourful) using the glass plate instead of the transparency holders.
How is this possible? The scanner is calibrated using a transparency holder.
Of course... using the glass plate quite often causes Newton rings. Is there a way to avoid/get rid of them?

Re: Scanning transparency (pos or neg)
Hi there,
Film stripes are inherently curved, if you use a film holder without glass, this curve makes the focusing point difficult because scanners have a very shallow depth of field. Using A glass holder reduces the focusing problem.
Right! The best way to reduce Newton rings is by wet mounting the film.
Cheers
