I have 1000mL of Unicolor C-41 chemistry mixed up and ready to go. If I use 200mL of solution to process one roll of c-41 and one roll of e-6 in the same batch and put the 200mL back into the container (I need the full 1000mL for some processes) will it ruin my c-41 chemicals? The chemicals are pretty fresh and this is the first time cross processing with this batch of chemicals.
