I recently developed two 35mm films together in a tank. One, and only one of them, came out with artefacts on most (but not all) of the exposures – spots of uneven development that seem to originate from the film sprocket holes. Here's one frame from the roll for illustration:
(Negative digitized using a digital camera; you can just about discern the film sprocket holes behind the improvised white mask.)
I'm new to film processing, having developed ~10 films so far; I have never encountered this problem before, but it looks to me like an agitation issue. The procedure was as follows:
- Loaded two 35mm films in a Jobo tank, one reel on top of the other. The films were Ilford FP4+ rated at EI64 and Fomapan 100 rated at EI100. The film with the problem is FP4+; Fomapan came out perfect. I don't remember which film was on top.
- Developed in 1:4 Ilfotec DD-X for 8 minutes in 20°C, following Ilford's recommended agitation routine (4 inversions spread out over 10 seconds every 1 minute), except that at one point I had a bit of a lapse of attention and there was 1½ minutes between two successive agitations (and then only ½ a minute before the next one).
- Stopped in Ilfostop.
- Fixed with 1:4 Ilford Rapid Fixer, 2 or 3 minutes.
- Washed using Ilford's "fill tank with water, invert n number of times, pour water out, repeat, repeat and repeat" method.
My specific questions:
- What caused this artefact, and why does it appear on one film only?
- Would the order in which the films were loaded have an effect? Is the damaged one more likely to have sat at the bottom or at the top?
- What can I do to avoid this sort of thing in the future?

Now that you mention it, I do remember that when I opened one of the film canisters, the film seemed to be "sticking to itself" in a way I had never experienced before. I don't know if it was the FP4 or the Fomapan, but I suspect the first. I didn't think much of it at the time – just thought this was characteristic of this type of film (which I had never processed before). Apart from that, same camera, storage and handling and both films exposed maybe a week apart. I should perhaps also add that the films went through airport security (carry-on bag) between exposure and development.

This looks to me as if you have botched loading the film onto the spiral, so that two wraps of the film were touching or very close to each other. When that happens you tend to get marks on the negs where developer hasn't really reached them properly.
(I tend to get this with 5x4 negs processed in a mod54: huge negs like that are very flexible so if you agitate too much they can come out of the slots and end up resting on each other.)

I concur. This is a film loading error. I don't think you can save the damaged frames but -- do try re-fixing in normal room light. This procedure might provide some improvement. Do try!
– Alan Marcus
yesterday
This is a good suggestion: if the dev didn't get to the frames then probably the fix did not either, so it is worth dunking them in fix for a bit to make sure they really are fixed, if you intend to keep them. As Alan says you can do this in white light.

Many thanks for your answer, @tfb! I'll make sure to pay more attention to loading the film properly next time. @Alan Marcus: thanks for the suggestion! I tried re-fixing today. The negatives didn't improve visibly, however.

PRACTICE with an old strip of film in the light, then in the dark . It should be loose feeling in the reel, give it a gentle push in towards the reel after every turn around the reel to see if it is binding up. You should be able to push it in and out a few millimeters. If it does not have the "right feel" then back it out a little and retry. After much practice and experimenting you will know the "right feel"

PRACTICE with an old strip of film in the light, then in the dark . It should be loose feeling in the reel, give it a gentle push in towards the reel after every turn around the reel to see if it is binding up. You should be able to push it in and out a few millimeters. If it does not have the "right feel" then back it out a little and retry. After much practice and experimenting you will know the "right feel"

The films were both exposed in the same camera, yes? With similar storage/handling before/after exposure? Any other differences between the films before you got to the point of starting development?

Now that you mention it, I do remember that when I opened one of the film canisters, the film seemed to be "sticking to itself" in a way I had never experienced before. I don't know if it was the FP4 or the Fomapan, but I suspect the first. I didn't think much of it at the time – just thought this was characteristic of this type of film (which I had never processed before). Apart from that, same camera, storage and handling and both films exposed maybe a week apart. I should perhaps also add that the films went through airport security (carry-on bag) between exposure and development.

Can you describe the specific error in text, to make it easier for people with similarly problems to find in the future?

If one of the films was 'odd' out of the can, then it's likely the Foma. I love Foma (particularly the papers) but their film bases are not as good as Ilford's: they're often a significant pain to load.
