I have a question regarding thick (double) emulsion films. I know that this kind of films contain two emulsions, one fast, and one slow. But, do these two emulsion develop at the same speed? IS it possible to overdevelop on emulsion and underdevelop the other? How would this effect the film curve and tonality? I use Fortepan and Verichrome mainly and I want to get the best of them. I noticed that these films render better tones when they are developed to a density above the average. I was searching the net for any articles regarding this kind of emulsions but I didn't find any!(posted 8206 days ago)regards xosni
