Did anyone work with Delta 400 in MF at EI of 3200 ? I bought some expired film, and was intending to try it out with D-76 (but I have some Rodinal availabe as well) for some evening/low light photography. Would it be more worthwhile to try with Tri-X instead? I'm looking mostly for good contrast without too much blocking in the highlights (within the limits of push processing, of course).
