This sums up my situation


Certain films are more prone to curl than others. Certain B&W chemicals will cause film to curl more than others. One of the reasons I switched from Tri-X to HP4 and then HP5/HP5+ (way back in the '70s) was that HP5 did not curl as much.

C41 color negative films usually stay very flat. Slide films (E6) tend to curl.

Back when I burned through hundreds of feet of Ektachrome for a living, if you put a paper or plastic mounted slide in a projector, it would pop as it heated up, throwing it out of focus. So those of us doing multi-image (simultaneous projection of multiple slide images in synchronization to a sound track) used glass mounts to keep the film flat. Cleaning six surfaces each of 960 slides for a 12-projector show meant cleaning 5760 surfaces! I can't tell you how much I love digital video...

just got an Epson V850 scanner; 1st attempt at scanning 35 negs years ago resulted in 2 low a resolution when I sent negs to print labs; suggestions appreciated

lot of 35 negs badly curled; only suggestion I found on web is to wet them and hang them with weights; this was not successful - anyone have a better idea ?


look up wet scanning on on the internet with ScanScience https://www.wetmounting.com/Pages/contact-us.html
