Hello! I have some unopened TMax RS developer that is about 2 years old. The instructions state that unopened developer is good up to two years. Should I throw it out, or will it stay good for a while? Thank you and best regards.

If you have some film that you might be just experimenting with or some film that's been laying around waiting for development then I'd use it up. But if I had some film that was important or I was running tests, I would feel much better using fresh chemicals. Tmax RS only costs what... $13? I'd throw it out and mix up a fresh batch. Remember, consistency is key is photography
