I have always shied away from developing my own C41 because of the very short development times and (to a lesser extent) the high processing temperatures. My very few attempts were less than satisfactory. Does anyone know of a brand of C41 Chemistry that can be used in the 20-22 degrees Celsius range and have a developing time of around 5 minutes.

My local processor (who is very good) can turn 35mm films around in about an hour but takes a week to process roll film. Changing processors is not an option
