I've searched all over the internet and can't seem to find the answer, or maybe I'm just not wording it correctly. I'm not sure what all information I need to share, so please let me know if I have not given enough.
The alternative process photography class I'm in right now is working on vandykes. Some people are having prints turn out a very cool brown as opposed to a warmer brown. The only reason we have narrowed it down to is that the UV box has to warm up and it's the first prints that are exposed while it is warming up that has this cool brown.
Our Washing Process:
We wash the prints first in distilled water with a little citric acid, then a tap water bath with some citric acid, a fix bath, and then a continuous water bath, then dry.
Has anyone else experienced this temperature change in their browns?
