The Kodak data sheet for T-MAX concentrate says that it is good for two years. Does this apply after the bottle has been opened or is this for an unopened, full bottle.(posted 8339 days ago)To be more specific, my normal way of working is to mix up only as much of the concentrate as I need to develop one or two rolls of film - whatever I happen to have ready to develop at the time. I have a bottle of concentrate that I started to use about two months ago. It is probably more than half full. Is it still good?
