Guys,
Just developed a couplf of rolls and major grey streaks and blotchy foggy patches runnign the length of the roll...within these blotchy greyness are streaks running verticlally seemingly from the sprocket holes....never seen this before, - but in general, a large splotchy grrey fog meandering up the centre of the roll of film.
The one I did last night had the same thing,just a milder version of it,; todays roll is a disaster area.
Within this mess you still have the photos underneath all this, just unprintable.
The fixer seems to be alright, it clears film leader in normal time.
I am wondering if my Ilford film developer has gone off. The bottle is only about three weeks old though....
Another possibility is there is a crack in my developing tank maybe, fogging the film...I have noticed it seems to drip chemicals from the bottom evrynow and again, Ive had it for twenty years.
Does this sound like bad developer or a light leak somewhere, - perhaps when loading the film into the tank? (Field expediant darkroom)
It doesnt look camera related. The film is Fomapan 400, the relatively new dev is Ilfotec LC29

I've just developed a few rolls with some LC29 that was opened a year ago, so I doubt that would be the problem.
Perhaps a bad batch of film? Can you test your workflow and chemistry with a different film from a trusted source?

Chris for the moment the best I can do as a control is to develope another roll in another spare tank that I have. That would eliminate that part.
Your right I dont think it would be the developer. Well, it really shouldnt be...
Just never seen it before, on one hand it looks chemical related, but on the other hand, with streaks coming from from the sprocket holes indicates light related. Confusing. I have never really had any problems with home devloping film since many years. THis is the first major issue.
The roll we looked at last night with the milder but similiar issue I was tempted to describe as bad film, but along with todays effort I am just not sure.

I have a bulk roll of 35mm film (Kodak Hawkeye Surveillance film) that is several years expired with dubious storage history. It has some kind of deposit on the shiny side of the film, perhaps transferred from the emulsion. The deposit appears as a patchy haze, but the negs are mostly usable, and the deposit can be removed with methylated spirit after developing. I wonder if you a problem like that? Can you sacrifice a short length from another roll of the same batch, to check? On mine it's clearly visible on the undeveloped film.

develop a different brand with the same dev and then the same film with a different dev. sounds much more likely to be the film than anything else.

No, this is not something on the surface that i can remove, its developed like this....I can even see that dense amounts of this 'fog' have gathered and filled in shadow areas...(which is why I thought it might be devloper...)
What about condensation? From being in the fridge and then taking it out, maybe condensation inside the film cassette? That shouldnt matter though I would think, the water would just mix into the developer solution I would have thought.
(I keep unexposed film in the fridge in a plastic bag, but for the first time this year because I knew I wasnt going to devope these for a while I put the exposed film in the fridge - but not in a bag...Im reaching here.)
When I can find some batteries for my evil digital camera I can post a photo, its obvious enough for me to be able to photograph the roll so you can see what it looks like.
Mu probelem is that I have some important film to develop that I have a deadline on Monday so feeling pressed for time to find a solution. I have a handfilm of other rolls I can develop, although it pains me to experiment this way.

is the important film stuff that is already exposed? I would run a quick roll of the same film through a known developer different to what you used last time. I hope it is not a film fault, but sounds awfully like either fault with the film or something that has affected it like chemical affects/fogging.
have you film from the same batch you can now go out an expose and quickly devlop?
I cant imagine it is the dev as this would have a uniform effect, such as poor development, fog etc

Is the "grey fog" milky grey, somewhat opaque, and a little bit the color of undeveloped film emulsion? If so, you loaded the reel incorrectly. Re-fixing the film will clear this type of fog but will probably not reveal any additional image detail as the unfixed areas were also undeveloped.
If the "grey fog" is a neutral grey exactly matching the grey characteristic tone in a normal exposed and developed image then you have a case of light fog that occurred at some time before development when the film was wound somewhat tightly against itself, as evidenced by the pattern around the sprocket holes.

Any chance that you can take a photo of the negatives ... either a digital shot or a scan?.

I had a bunch of film go through an antique X-ray machine in Syria, where the rolls god *slammed* with radiation. Some of them looked like your description (unidentifiable blobs), but the patterns were erratic.
