what do you mean converts it?
The good thing that Orwo and Agfa paper lith wonderfully in the main - whatever their age
You may not get an answer as this person has not visited for nearly 5 years. She was a fairly frequent visitor before she stopped visiting. Might be worth using "create a conversation" if she hasn't changed her e-mail addressWhich developer / concentration are you using? My Orwo liths nicely, but gives almost no colour.
My experience of Agfa paper is that anything with "Speed" in the name is likely going to be fogged. Plain Brovira, though, has been holding up really well. The fiber based papers seem to fare much better than the rc papers. I think the advanced age-fogging of a lot of papers is the result of accelerators in the emulsion that speed up exposure - i.e., make the papers "faster" - and additives that control contrast. Lower contrast papers tend to age poorly, just as higher contrast papers age well but lose a grade or so of contrast. The lesson there is that there is age fog even if it's not completely visible on a developed/fixed sheet. It results in a muddy print.
I add extra potassium bromide to developers all the time since I use so much expired paper. But I must say that, when I use a new sheet of Foma or Ilford fiber paper (especially the Ilford warmtone - I like that a lot), there is a level of satisfaction that exceeds the inverse of the frustration I feel dealing with older paper. I can put up with the frustration and enjoy the new paper all the more for it.
I'd like to try Orwo paper - but I've never had the chance to buy any.
I had to add about 15 ml to a litre of WORKING strength developer
Ah, thanks for that info Don. I didn't know either of those points, although I generally ditch the small amount of home mixed D72 that I make regularly, after about a two hour printing session.That's probably what I usually end up putting in. I find benzo kills developer within a few hours, though. You can definitely put in too much. It can be good to add extra sodium carbonate solution to boost the alkalinity.
