The second set of images certainly look like a clear improvement on the first.

When you mentioned about horrible things in evenly toned areas such as the sky, does it appear like a clumping, mottling effect?
If so, this is quite a common phenomenon and is generally a sign of film that has been poorly stored and exposed to heat and moisture.

The antifogging "Restrainer" from Moersch shouldn't be expensive.

The traditional antifog chemical has been and of course could be Kaliumbromide.

I have had a bit of clumping but also black spots and the odd scratch. I think it is pretty much beyond redemption but is good enough to test eBay purchases

From the resulting solution add 10cc to the working developer (I does not say what the quantity of working solution is (?) which will take some experimentation. It does not mention any change in developing time though.



I was wrong about speed being restored in fact the speed from the ORIGINAL is reduced



I would think if you feel a bit of experimentation, where to start to look for the places that sell it be Silverprint, although Firstcall sell something with a similar name (1-phenyl- 5-mercaptotiazole) it is sold under the manufacturers name of Belini but is quite expensive.
Its all interesting stuff. I read the same article on photrio. I have five rolls in the freezer so may just pick up some anti fogging agent and have an experiment. Thanks for this info

I bought a lovely Fed-3 and tested all the shutter speeds with the FP4 safety film. This time I shot at 64, developed at 250, like last time but this time I added 10% to the dev time and I am rather pleased with the results. Its still a bit grainy but this is eminently usable. I won't be shooting with it when I have a purpose in mind but when I am just parping around its ideal
