...across slides. I know this topic should belong to the color section of this forum but I'm posting here because I hope it gets much more exposure (no pun intended!!!) Here's my problem: as you can see from the crappy image attached (which I've made with my webcam - please don't shoot in my back ), several slides have this white faint line across them. I've tried to clean them in every possible way, to no avail. What I've tried is: 1- cleaning with photoflo 1:200 2- only photoflo with a cotton swab 3- with an electronic contact cleaner 4- only distilled water The slides have been developed by a professional lab here in Rome, Italy, where I live. I can argue the faint line is a stabilizer leftover but I cannot remove it. Ah, last thing: Pec-12 in NOT available here. What can I do to salvage these slides?
