I'm puzzled over my inability to print clean photos at enlargements over 10x. I can see and deal with large particles of dust. Proper dust is a problem I can handle. If I can see it, I can get rid of it. But sometimes I can't even see what's causing it. The latest 11x14 image I printed from 35mm had light flecks all over it, even though I could not see them on the light table through my 50mm lens-loupe. It's reasonable to conclude that I just couldn't see the little particles that were causing it. Attempts at cleaning the negative with compressed air and kimwipes, culminating in aggressive scrubbing with an isopropyl lens wipe, usually just herded the flecks around the negative. Now it's possible that the emulsion is damaged from the scrubbing. Should I buy some purpose-made Edwal negative cleaner? Rewash the negative in distilled water and photoflo? Get a microscope? Give up and spend hours spotting little grey dots all over my prints? Go over to the dark side? Stop printing 35mm so big?
