Sometimes I get wacky ideas soaking in the tub at home. So I dried off, taped a couple of negs to my laptop screen, took photos of them w/ my phone, emailed them to myself, downloaded them into a folder, and played with the files in Photoshop.
The 6x6 neg came out pretty well because it was well exposed, but the phone was picking up the grid lines on my laptop screen, so this would work better w/ a light table (or a homemade one, and that's the next project).
The 6x9 neg came out crappy because it was under exposed, and there's only so much you can do w/ a handheld smart phone used as a scanner. But I think that if I had a proper light source and well exposed negs this might work well enough for emails and basic proofs.
