cviviani Posted October 6, 2012 Share #1 Posted October 6, 2012 Advertisement (gone after registration) Dear All, I am having issues with my Canon MG8150 all-in-one scanner. As you can see, there are visible (and annoying) stains at the center of the image. I cleaned thoroughly the scanner glass and checked the negative (clean) but to no avail. Any suggestion would be much appreciated! thank you Carlo Link to post Share on other sites More sharing options...

peterbengtson Posted October 6, 2012 Share #2 Posted October 6, 2012 If you are scanning a black and white negative turn off the "Digital Ice" dust reduction. It does not function properly with silver based films. I hope this helps. Link to post Share on other sites More sharing options...
philipus Posted October 7, 2012 Share #3 Posted October 7, 2012 The ones to the left look almost like the kind of moiré one can see on an LCD screen. However, judging by the shape of the marks the middle-right they are marks from the development liquids which haven't been properly removed. They ought to be visible on the neg, possibly with a loupe. Link to post Share on other sites More sharing options...
Lightwrangler Posted October 7, 2012 Share #4 Posted October 7, 2012 Looks like Newton's rings. Does the negative have direct contact to a glas surface? P.S. Just saw it's an all-in-one scanner - so glas! Not much you can do I fear. Anti-newton-glas would be the solution, but not applicable here I suppose?

P.P.S Found some tips here: How to Avoid Newton Rings While Scanning Your Negatives - Lomography Mike Thank you Mike - I have made a little research and I agree they're Newton's rings. The trouble is that to scan the negative I have to use the supplied adapter and if the negative is curved it will touch the glass. The alternative I can imagine would be to reverse the negative but then I lose some resolution. I will try the trick suggested by the site and report back. Thank you for your help Carlo Link to post Share on other sites More sharing options...
Lightwrangler Posted October 9, 2012 Share #6 Posted October 9, 2012 Easiest, Carlo, would be to buy a decent negative-scanner. They are not so expensive after all and spare you a lot of hassle. Otherwise - maybe you could flatten the negative between silk paper and heavy books overnight? Or is there a way to subsitute the adapter by a newton-glasplate? Hope you find a solution.
