Processing film in my darkroom I'm getting blurry spots along the edge of my negatives.
They appear as darks spots on the scans, white spots on the negatives.
Photos of both negatives and scans are attached here.
It is only along the edge of the negatives, never in the middle.
They are blurry, cloudy spots. Always random, not every frame from every roll has them. Some rolls I process don’t have them at all.
Appears on Tri-X and HP5 both so isn't film-related.
I used to get this problem with the plastic Paterson reels and tanks so I switched to stainless steel and I’m still getting this problem, thought with less frequency.
Processing / Chemistry Details:
Sprint Standard Developer / Sprint Speed Fixer / Sprint Block Stop Bath / Sprint Archive Fixer Remover.
Pre-Soak with Distilled Water.
All Chemicals mixed with distilled water, including developer.
Only the final rinse is done with unfiltered water.
Normal to vigorous agitation.
Any help is appreciated!
