I am shooting at my mother's family farm Monday prior to it being auctioned in December. The weather looks like it will be overcast at best, I am looking for advice on the best ways to rate my films to get the best negs I can. I will be contact printing 8x10 and 5x7 as well as shooting some MF with my Rolliecord. The films I am using are: 8x10: JandC 200, typical ei@100 5x7: TMY (ei400) and FP4 (ei100) MF: TX, Foma 100, and EPY all at box speed. available developers: HC-110, Rodinal, Pyrocat HD, Diafine Should I lower my EI and overdevelop to increase contrast? or just go with what know and work on it when I print?
