As mentioned in another thread I had run another roll of 120 size Fomapan 200 through my TLR to see if the use of an alkaline fixer would reduce the issue I've been having with black spots, etc with this film. It didn't but I did have another issue with developing this time as shown below - banding showing up in the light areas like the sky. The effect was most prominent in the exposures towards the middle of the roll, the boathouse in the second image was at the start of the roll and the house in the third image at the end (although faint banding can still be made out).
It's not a scanner artifact as the banding is easily visible on the negatives.
As the film sits in the tank (Paterson System 4) the banding is in the horizontal, not vertical direction, and I'm wondering if it is down to using the 'twizzle stick,' for the first agitation interval, thereafter periodic inversion agitation was used. Developer was Ilford Microphen (6 minutes at 20°C) and a 3 minute prewash was used. This prompts another question, is a prewash advisable?
Any other ideas as to what would cause this banding and how to avoid it in the future?
