I'll definitely give this a try. I double majored in photography and American photography history in college (I know, super useful... now I work in tech). I had my own darkroom. What I loved to do (and would love the ability to do digitally) as to blow out the whites and make the B/W contrast a max while combining multiple negatives at once. Sort of like a collage, layering the negatives on top of each other. Can you do that in the app? Also - I'm sure - is it easy enough to convert any color image to B/W and adjust the levels?
