I have a box of 4x5 Tri-x that expired in 1992 and was wondering what speed should i shoot it at? A year ago i bought some misc darkroom supplies from a retired photographer and included was the box of Tri-x and a box of fiber paper that also was from 1992.. The paper had zero fog so im hoping that the tri-x will be fine also but if it isnt what should i do about the speed? The only developer i have at the moment is Rodinal... Thanks..
