So I have an otherwise great neg of an important image I started printing last night. This is from Rollei IR400 in Rodinal that probably needed to be pre-soaked as it has some weird streaking in a few frames. Well, I thought this image was clean until I made a 10" print in which I found a straight semi-hard edged difference in neg density, in sky. It is pretty minor in terms of percentage, but it is there and would render the print unsaleable If not corrected. The only thing I can think to do is make a mask for it and just give it a try. It is even in terms of being consistently and slightly denser in the left 1.5" of the print, it already looks like I masked it. Anyone else salvage this kind of problem?
