    Green blobs on negatives; any hope?

    I've just gotten a roll of Superia 400 back from the developer (a minilab at a place where I've historically had good luck with the results---I don't shoot enough colour to justify doing my own). I had them develop only and return the roll uncut, for reasons not germane to this discussion, and when I got the roll home, I discovered that there were several substantial areas of blobby green colour on the negatives.

    I can't see any particular pattern to how and where the green appears; it doesn't follow frame lines, has no particular consistent shape, and seems to overlay rather than replace the image---I can still see the actual image, but stained green. The edges of the discolouration are distinct in some places, and in others it fades away with no clear boundary. The total affected area is maybe 10-20% of the roll.

    The store's processor is something called an AKS 19 FP, sold by the somewhat weirdly named "KIS Photo-Me Group", and as I say I've gotten perfectly good results from them in the past. The guy who did the processing is off until the weekend, when I'll go back in and talk to him about what happened, but in the meantime I'd like to solicit APUG's wisdom. Is there a standard cause for this sort of thing, and is there any hope for recovering the affected frames? Bleach and redevelop, or something like that?

    The images aren't particularly critical, fortunately---there are a couple of pictures of my son that I'd like to recover, but it was just a "messing around" roll.

    Any thoughts?

    Thanks

    Maybe PE or others can be more helpful, but your first line of approach would be to talk to the processing people at the store.

    Sounds like some kind of contamination.

    KIS are a medium sized manufacturer of processing equipment, problems with colour processing are usually down to poor maintenance and operator errors.

    Wow, thanks for the quick wave of responses, everyone.

    I'll talk to the processing guy (the lab supervisor is the one who ran this roll, and from my past interactions with him I think he's a reasonable guy who actually gives a damn about film processing) when he's back at work. Mainly, I'm trying to find out if there's anything I can expect him to *do* about it, or if I'm just registering a concern and maybe getting a free roll of film or something.

    Someone suggested redoing the bleach-and-fix step. Is that something I can expect the minilab to be able to do, or am I on my own?

    Thanks

    There are 2 things here: bad processing and bad wash, maybe dirty rollers.

    AFTER you have spoken to the guy from the lab you can roll this film in a reel, let it soak for a minute and apply a luke-warm shower to it and see if the green stuff disapears.
    If it is just on the film carrier you can try a wet cotton swab under running water.

    If you do anything that rewets the film, remember that the last step must be to give it an authorized Final Rinse or it will have image stability problems.

    Otherwise, I could not hope to guess at this point. The dyes will shift color with extremes in pH, but if this were the case, they may be ruined. IDK. Can you post a scan?

    If the guy knows how to trick the equipment, then yes. At least on fuji equipment, you can trick the lid sensor of the film processor and put the film attached to a leader card back into any chemical instead of starting at the developer. He may or may not know how to do this, and this may or may not be possible with KIS equipment.

    Here's one of the more dramatically affected frames. In this one the discoloration spans the whole height of the frame; in some others it's only at the bottom. It spills across into the rebate and all the way to the edge of the film---unfortunately I already cropped the scans.

    Look like anything?

    Thanks

    What kind of camera? If it is a Hasselblad, based on this one photo I would suspect a problem with light seals.
