I'm using PanF+ and developing in rollo pyro. Unfortunately, I haven't found a recommended time for this combo. I went with 7 min as a decent guess based on the book of pyro and times for pmk. I develop Delta 100 at 8min and I'm good there. I'm new to enlarging and just had my first session with contrast filters. To get the look I liked, I had to use a #5. Say I wanted the whole roll of film to have that level of contrast. Is there an adjustment I could do during film development?(longer, shorter). It stains so much differently (less) than the delta so it's hard (for me) to judge. I will be using more filtration when taking the photos and do some tests there. Or is it just better to do the contrast while making the print? Thanks for the help!
