I have a roll of Tri-X that I've kept around for many years, unsure of which developer to use. I was in the unfortunate situation of capturing an image from too far away, yet this is a high school graduation picture and I would like to be able to enlarge it to make a useable print. This roll of Tri-X 400 was shot in great light and was exposed properly. I am looking to reduce grain and enhance both sharpness and acuity. Does anyone have a recommended developer? Kodak is vague on X-Tol; I also was thinking about Acufine and Diaphine. Any recommendations would be greatly appreciated!
