What camera?I've recently experienced these 'black spots/marks' on Fomapan 200 (120 format - Batch 012956 1). Developed in Rodinal 1:50 with 1 min weak acidic stop and 5 minute fix and wash
The attached crop is but one example.
I developed Fomapan 400 on the following day (also with Rodinal) and the image are all clear of such marks.
Like others, I've requested follow-up from Fomapan on the cause / remedy.View attachment 269712
Franka Solida III (the model with uncoupled rangefinder)What camera?
Is it definitely the film though? I had a very similar issue in the past with a Braun Paxina and multiple rolls of FP4+ i put through it. I eventually discovered the flocking paint was coming off and settling on the emulsion.Seems a lot of older folders have this issue, just too soft of an emulsion for them. @Lachlan Young
I had it in two camera's now, my Bessa 46 and Isolette II. It's only with the Fomapan 200. In 120.Is it definitely the film though?

What makes the folders prone to this issue? I've just a roll from the same batch into my ETRS to see if I get the same problem.
Possibly the way the film travels and what it touches?

I think it may need further investigation, if only to eliminate it as a cause
Yes @markjwyatt, that's citric acid - 1/2 teaspoon in 500ml distilled water.@**Walter mentioned he used a "weak acidic stop". Would that be citric acid? That is what I have been using. I have 4 rolls of Foma 400 in 120. Good to hear the one roll was ok.
I have to agree, although I've used a fair amount of 100, 400 and also 200 in various sizes from 35mm up to 8x10 often to my satisfaction. 100 and 200 are fine films particularly in 4x5" IMO. In 35mm both 100 and 200 are low cost options that give little to no trouble, but keeping in mind that it's quite old tech, so for the critical user it'll be very noticeable that it isn't tmax, delta or even fp4+. The 100 also does very well in 120 format, but I personally stay away from the 200 in that size due to the issues highlighted in this thread, which sadly are a recurring problem with this particular film. The 400 I'm not a fan of; too slow and grainy for me. Haven't tried the 320 and don't plan to, either.Foma does seems to have more issues than others.
For those of you have never had QC issues with Foma great. How lucky for you. However, for me and all the others I've read about of the years who have had faulty rolls I guess it just sucks to be us. Look, maybe Foma is happy to replace defective rolls. The last time I tried to give their 100 iso film a chance I bought about 30 rolls of 120 and within the first several rolls I had odd markings on the film. Mind you I have been developing and printing for almost 20 years now thus I don't think it was user error. I sent the remaining Foma rolls back to store I ordered them from. Sure Kodak and Ilford may have had issues in the past but not to the extent Foma has. The bottom line is I cannot go back and re-take a picture I previously took because I'm using a film that didn't deliver for me. I've never had any issues with Kodak, Ilford, or Fiji films so it's a no-brainer to me to stick with those choices. We take care of our cameras keeping them properly serviced so we can rely on them and use them with confidence. To use a film that has a bad track record seems to defeat this purpose and honestly I place too much importance on my work to take that chance. As always, your mileage may vary.
