What's gone wrong here?

[Muggins]

I've just got a film back from the processors with white spots on two of the negatives, red when reversed. Pic below. Any ideas? My guess is a light leak and for some reason it's gome through the markings on te paper, as they're adjacent frames, but I don't have a Portra 120 backing paper to hand to check.

Bright ideas welcomed.

Thanks!

I've no present idea re the source of your spots. However, if they were from light leaks, would they not be dark on the negative and white on the positive image? Do they appear at the beginning of the roll? So far, my best guess is some unknown (to me) processing error.

what camera is this from ? but yeah, as randy noted, light leaks would be overexposed. my initial guess, until we get more info, is processing error of some sort. it's a reach, but there you go...

Camera is a Moskva-4, spots are on shots 4 and 5, taken abbout three months apart.

Intriguing. The spots are dark and so must be some damage to the emulsion. They are all the same size. Must have been a machine that did this. They are in line with the long axis of the film. The period between spots is not geometric and so the pattern looks random, not related to the rolling of the film at manufacture or in processing. It would be of interest to see the other frame and know which was 4 and which was 5. Looks like it must be a processing problem. Even if you used an awl to cut the tape to release the leader paper you wouldn’t have done this yourself. Was this a big lab with some automation? Could this be Kodak’s fault at manufacture of the film....?

Don't know how it was developed but if the reel was loaded poorly and the film was touching other film, then developer could not get to the emulsion and could cause shots like this. Shots 4 and 5 would be near the start of the reel and could have touched each other.
