fogged fiber paper and potassium bromide

[zsolt]

Zsolt, I've tried KBR and TAF-1 (a product from Photographer's Formulary) and now I'm using the Moersch stuff. All of them work. I just found my development times getting longer than I like with KBr and Taf-1. I also like the ease of use. I get a bit impatient in the darkroom sometimes. Seconding the lith thing. I've lithed 1930s paper that was impossible to use due to intense fog and gotten beautiful results with a wide range of tones and pure whites.

Ok,Gentleman,i admit..i bought today a rollei lith developer,and going to use it on the really gray fogged paper,and to be honest,really looking forward to it!selected already approx 30 4x5 negatives with lith in mind.
i looked into the Moersch stuff,and as far as i could find on the net its 4% benzo with DIETHYLENE GLYCOL 15-20%
so tomorrow..lith,here i come
Thanks for the suggestions Greginpa!

I have no idea why your KBr stopped working. I'd try adding more in small increments to see if that worked. If not, start over and try using benzotriazole to see if that works better as a restrainer.

Finally, if you can't get rid of all the fog at the developer stage, you might want to try bleaching a print in a weak solution of potassium ferricyanide and potassium bromide (or you can use a weak Farmer's reducer; pot ferri and sodium thiosulfate, but it doesn't last long) to clear the whites. I've saved some fogged paper this way with good results.

FWIW, adding more restrainer will slow down the developer and require longer exposure times, but shouldn't affect the contrast of the paper.

Best,

Hello Doremus!Thanks for the ideas!
to me it was a mistery too..BUT today tried it again,and it worked like a charm,today the paper had a better mood i guess.
had to give 160ml more to the developer,and the exposure changed from 20 sec to 75sec,but it all worked out well
made 2 printsim really glad!!
no idea what could have happened yesterday
measured everything to stock solution..mistery..
btw..tried bleaching with ferri,but (as i experienced before too)bleaching is not for me..(not yet..)
i still have to try the bleach that Ansel mentions in his book "The Print" as he says i quote "it has a very little tendency to cause stains"
Thanks Doremus!
AlltheBest!
