Hello -
I am struggling to understand what might be going on with my developing, and am looking for suggestions on what I should be looking for to solve the issue. The image was taken using Fomapan 100 classic. This image was using a Crown Graphic with a 150mm 6.3 lens at f/32 for 1/15 second.

Developed with Cinestill DF96 monobath at the recommended 80 degrees F. The developer is unexpired and had just 3 35mm rolls and 2 4x5 sheeds developed in it previously. It has been open about 2 weeks and kept at room temperature. I developed using a Patterson tank with MOD54 sheet holder and developed six sheets. Same issue on each sheet. I pre-rinsed with 80-degree F tap water until the water ran clear, then developed for 4 minutes 15 seconds, rinsed for 10 minutes. I then did a final rinse with photo flow (about 3 drops per 2 Liters of 80-degree water. I used tap water that is not considered hard water (Tacoma area water from local river watershed). This has also happened in a Stearman tank.

Thank you for your ideas.
