I tested my C-41 chemical with an unknown roll of film from a camera I purchased a while ago. I did not shoot the film, so I do not know much about it. It is a Kodak max. The film looks over-exposed. It looks too green. The CN-41 chemicals are old (open bottle concentrate) and I was thinking of dumping the open bottles and restart from sealed bottles. I do not know if the chemicals are bad, or just the over-exposed negative. The film was scanned with Minolta Elite 5400 film scanner.
