Staining
Asking people on the Forum is a good idea but without the technical back up from the manufacturers, there can be a number of false reasons for your problems that only FOMA can really give a definitive answer.

Hi Neil-
Film developed emulsion side UP. I couldn't bring myself to process emulsion down for fear of damage. John- so obvious I didn't think of it. Foma have a website with contact email. I'll drop a message to them. |

I have had a stain similar to the one you have shown on the back of a sheet of film. I assumed insufficiant washing caused by sticking - the blobs cured the problem. Neil.

Hi Neil.
Yes, I have experienced sheet film sticking to the bottom of the tray and consequently having purple blotches on the back of the film at the end of processing. It has never been the whole sheet, and easily washed out once the film was peeled off the bottom of the tray. This might sound bizarre, but the more I look the other 3 sheets seem a little less stained than normal. It's almost as if this 1 sheet preferentially 'sucked up' all the stain. As John suggests I'm going to message Foma, but I don't expect a quick response. Just home, so might try exposing and developing another couple of sheets from the new box tonight. Cheers Colin |

Colin,
It could well be tech issue but would Foma admit to this? Interestly my Foma 5x4s have all been problem free with tray dev, which I only do now. The problem I had with the occasional sticking sheet was with HP5+ ! But the blobs conversion sorted this out. I have used a fair bit of 5x4 Foma 100 (@ ISO 50) with no problems but have now moved to Foma 200 on 5x4. Neil.

Hi Neil.
I did dabble briefly with a Paterson Orbital, but I've been exclusively tray processing my sheet film for years now. My DIY slosher has a perforated bottom to allow chemical flow- the only time sheets have stuck is when doing a second round of film, and the film is going into a wet tray. I then occasionally get a bit of 'suction' and a sheet will stick. Would Foma admit to a technical problem? Of course they would, customer satisfaction is everything ps- I agree on ISO 50 |

Collin, It is looking like a 'one off' to me and you will probaly won't get it again. Some great results can be obtained with this film, hopefully Foma will have a look and advise. Maybe ...... Neil.

Hi Neil.
I think Foma 100 has a particular look to it. Although I've tried FP4, HP5 and some Adox in 5x4, all my favourite images have been on Foma. That could be pure chance, or a bit of imagination, but I'm sticking with it despite its occasional foibles. |

I have used the 100 mainly for alternative work where there can be, with me, a lot of wasted film to ge the density right for the process involved. But when I get the exposure / dev right I found it it works very well alround with good quality results. Neil.

Any company worth dealing with, if you have a problem they would be glad to help in case there were others. I think Ilford had a problem with the backing paper on 120 film and they took it on board.
