We have been discussing on another thread tweaks to an RA4 formula, and it has been established that reducing the amount of sodium sulfite and/or increasing carbonate can increase contrast in a print.

I was wondering if anyone has experimented with similar adjustments to alter contrast in C41 developing? I'm most interested to know if similar tweaks could cause an ECN-2 negative to develop with higher than normal contrast, without significant crossover, to assist in the normal printing thereof. For example, if I could up the negative contrast a bit, and up the printing contrast a bit, I could end up with a good print result. Any ideas?
