Every once in a while I come across a post here or elsewhere stating it is possible to selenium-tone Van Dyke Brownprints, but I have never seen an example image posted. I have been unable to successfully selenium-tone a VDB even when I dilute the toner 1+200 or more. The print always suffers from bleaching and ends up with a foul color and weak dmax. I have successfully gold-toned VDBs and believe I would have no problem doing so with Pt/Pd should I care to, but based on my previous experience, I really find it hard to believe I could get a decent VDB print with good density if selenium-toned.
Can someone please upload a side-by-side example of a successfully selenium-toned VDB and untoned VDB pair, or point me to images on the web that compare them?
