Hello, I've recently been using VDB again but with different results than I've had in the past. I made up a fresh batch of the VD and am using fresh thiosulphate, the results are not a strong brown and there is weak contrast. When I first rinsed the contrast was good but that was quickly lost. I did try pot. dichromate but that didn't do anything visible to the contrast. Any suggestions would be appreciated. Thank you. Anne
