Hello,,

What is the shelf life of "mixed" Rollie C-41 Chems?

Thx
Steve

I only have experience with the Fuji Hunt kit. I got through several sheets and rolls over the course of about 4 months before the color shift got too bad to correct in scanning. Shelf life without use will depend on many factors, including the quality of the water it was mixed with and the degree to which the chemicals are exposed to air. Another factor is the bleach/fix; if it's a single bath, it'll last shorter than separate solutions. I'd personally guesstimate the shelf life to be maybe 3 months if you're lucky.
