A question to the lith experts. I have noticed in the large highlight areas that I get a "texture" after selenium toning. On slavich it is quite fine grain and is not unpleasant, and gives the e.g. sky a kind of parchment look. Doesn't usually show up in scans as it is quite subtle.
However, just trying some Foma 131 and I get the same type of blotches but they are much larger and not as pleasant
The scan below is drastically manipulated to emphasise them and get them to show up - anyone know what causes them? Only thing I can think is insufficient fixing, but although I only use a single bath fixer, I do clip test it and track usage and tend to renew well before it is anywhere near exhausted. Also, I wash for 5-10 minutes in my washer between fix and toner so as not to contaminate the toner too much.
Anyone know the definitive cause? or is it just the effect of this paper. Lith developer is Moersch easylith at 17;17;1000 so about 1:30
