Have a bunch of prints I put in selenium trying to get a lot more change than normal. Mixed the selenium 1 to 20 and put the prints in. Very little change. Left them in with agitation for 20 minutes. Very little change. A bit cold toned but no reddish or warming at all. The prints were all developed in Michael A. Smiths' amidol and fixed in a non hardening fixer. They didn't change enough to tell and certainly not the warmth I was looking for. Guess I will have to go another direction & bleach & redevelop in sepia to get closer to what I want. Anyone know why they don't change tone much at all with such a strong solution of selenium & the long time in the bath?
