When I shoot a lot of film I am usually on vacation or a weekend trip so I take an extra day off just to process the negatives and proof the M/F and L/F and make 4X5 prints from 35mm. I then spend time selecting the negatives I really want to print (I also scan the negatives that show promise to get a better look before I print them in the wet darkroom). Last weekend I shot 2 rolls of 35mm, 2 rolls of 6X9 and 10 4X5, printed only 4X5, after a few weeks I will take a another look to see if I missed something. Unless there is an urgent need to produce a print right a way I tend to let some time pass before I look at the proofs or work prints with fresh eyes.
