you are forewarned this is going to be a post filled with praise.
what a great film. I just developed my first 4 sheets of 8x10 J&C Pro 100. Stunning film. Great latitude and the contrast and tone look wonderful in the negatives. I developed them in PMK Pyro (1:2:100) for 13.5 mins per their suggested starting times developed and exposed at N 100EI. cant wait for them to dry and to make some contact prints.
great film and well worth the cost (which was quite affordable).
the only blatant "learning curve".... scratchs fairly easy. need to be more gentle on the film.
