Hi all. Ever the penny pincher, I've today been given some out of date (year 2000!) Tri-x. Someone today said that the main problem will be loss of speed - I would need to rate the film at something other than my usual 400. Does anyone have any exact (-ish) science on this or even simply what I should rate this film at. I'm only ever after securing 'moments' so if the film's character has changed in any way, I don't mind. I just need to get a printable negative. Regards, PETE.
