Image Latency of different films

[bvy]

Besides Pan F, which films should I develop sooner rather than later? My backlog of undeveloped film has just crossed the one year mark (!). I have color (C-41) and black and white, 120 and 35mm, all types but a lot of Acros, Tri-X, Superia and Portra and some one off's like Kodak BW400CN. Thanks.

no idea.I never had the patience to wait longer than a day or two after exposing the last frame on a roll of film

I don't know if speed or tabular grain is a factor in how well they last after exposure? I would suspect doing the most expired first, the faster ones sooner rather than later, etc.. would be the best course. I had a growing pile that I knew I wouldn't get to before moving, so I just sent it all off to Prauss in Rochester. Got it back just after moving and it's all great. To me, it was worth the $ over the hassle. It would end up sitting for another year with all the unpacking and organizing I need to do.

If you are home processing, batch process all the C-41 and then concentrate on which B&W films you can do together using same times. I'm like Ralph, I don't wait. When ever possible, my film is processed same day it's shot. When I was much younger, my friends and I would shoot all day then stay up all night developing.

The stability of the latent image is a complex problem that depends on several things. Among them are

o The formulation of the particular emulsion.
o The storage conditions of the film, that is the average temperature and humidity.
o The duration of the storage before development.
o Speed of degradation is most rapid in the first few hours and days after exposure and then lessens with time.

Color films are effected more adversely than black and white films. Certain 120 films suffer print thru from the backing paper.

Certainly waiting a year or more to develop film is too long.
