Green Fog in film

[shicks5319]

I am having trouble with a batch Delta 100 purchased via mail order from B&H.

I am processing the film in Ilford Ilfortec HC (1+4) in a completely dark setting. My water temps are slightly high 72 to 74 degrees F but I am adjusting for that via Ilford's specs.

The film exhibits a heavy fog base the color of army green.

I am wondering if anyone else has had this happen and found the source of the problem. I have contacted B&H and they are not aware of any problems in shipping - this particular shipment came via UPS 0- 2nd day.

Thanks for your consideration on this matter.

What kind of shape is your fixer in? Colors like that are either dichroic fog or unfixed halides. Both can be caused by waek fixer or a weak or ineffective stop or water wash between steps.

I agree with Gary - looks like a fixer problem.
And refix in fresh fixer quickly - or the new fix will not last long.

years ago when tmax developer first came out i was advised to use tmax instead of "tmax rs" to process my 4x5 negatives. i got a mysterious greenish metalic "stain" on all my films. it was a "dichroic fog" (sorry if i spelled it wrong). the folks at kodak didn't know how to get rid of it and told me to throw away all my negatives ( GO KODAK! ). paul krot at sprint chemistry in pawtucket rhode island told me what to do. i mixed farmers reducer (potassium ferrocyanide with his fixer dilute 2:8). i put the film in hangers, let it sit for about 15 seconds and then washed ... if they were still fogged i repeated until it was gone. this eventually got rid of it.

i am not sure if you have the same green stains, or if farmers reducer will help you out. if re-fixing your film doesn't work it might be worth a try to see if the reducer will work.

That was it!! I went back over my steps and realized that I had inadvertently mixed up a label on the fixer as was using an old mix. I tried re-fixing a couple of rolls and the the negs became clear.

I can't say how much this was helpful. I would have chased that problem for a while. This is the greatest forum.

Thanks guys
