TMY to TMY-2... when?
People who know my history will laugh at my ignorance. Go ahead; here's my question.
When did Kodak change T-Max 400 to it current formulation?
I tested the original in '87 or so. We occasionally had use for it on the job, but I never used it for personal work. I do remember that it was big news when they improved the emulsion... but wasn't tempted to try it then.
Now someone has given me several boxes of 4x5 TMY, dated 12/2009, emulsion #561.
No one I know from my Kodak days still works there, so I'll put my question to the community; is this film the original version or the new and improved?
I've loaded holders for EI/dev time tests, so will find a working method for this film, but it would be interesting to know the answer.
