Even Ed has mentioned that you will not gain much, if anything from doing so. The noise levels aren't easily improved upon on the SS4000 and SS4000+, but if you have the chance to try it, let us know if you get any improvement without loss due to misregistration. I did try a multipass (x4) and long pass using the Minolta Dual II and there was some improvement in the shadows in terms of noise, but no real improvement in terms of dynamic range (more levels of gradients).

Arthur: >Even Ed has mentioned that you will not gain much, if anything from >doing so. It's that "little bit" that I wouldn't mind gaining. :) I'm happy with incremental improvements. Anything that will help the image. Don't get me wrong. I'm extremely happy with what I can get from my SS4000 and Vuescan right now. It's wonderful. I just want more. Always. :) I don't mind doubling the scanning time for any kind of visible improvement.

I have a Polaroid SprintScan 4000, and I'd love to be able to make multiple passes. Or even the long exposure pass.

I'd personally be happy to trade off memory (even a lot of memory) if the multiple-pass function became useful to me. Maybe it could be another option?

My Dual Scan 2 can not really benefit from multiple passes as the images are out of registration - though it's fairly low noise I'd always like it to be better. Manually adding/subtracting images is too much faff for me as the error is not consistent between scans.

Hi Ed, I believe similar techniques could be used to improve/enable multi-scanning on units with less than accurate alignment. This would certainly benefit many scanners. Is it practical - do you have the time ? regards, Steve PS Keep up the good work - good product - outstanding customer support.
