Big Bright Spots on negative (Fuji Neopan 100, Caffenol C-M)
I finally got around to processing my own film (I only shoot 35mm) recently, and here's a brief description of my setup:
Stainless steel tank and reel (1 roll at a time).
Developer: Caffenol C-M Reinhold's formula, with Bru Instant Coffee (I don't get Folger's here)
Stop bath: Acetic Acid diluted water.
Fixer: Agifix (A local fixer brand, specially used for X-Ray films)
Photo-Flo: Again, a local variety.
(All chemicals mixed in tap water at room temperature, and then refrigerated to get to right temperature)
I'm trying to follow all the instructions to the T, so temperature control, agitation etc. are all pretty standard.
Also, I use all the chemicals one-shot.
Now the trouble is, in every roll I process (3 so far), some frames invariably end up with a blot-like spot on them. Some others are perfectly clean.
Attached a few examples (some aren't true B/W because I scanned them as C41).
Any ideas on what I'm doing wrong?
Slightly less than worse (look at the bright white spot on left)
