I've been in awe of the work of Charles Jones for some time now after stumbling upon Plant Kingdoms at my local library. His blacks are so rich that they look like tarnished silver. If you haven't seen his work, there is a good representation here: http://www.nielsengallery.com/db/CharlesJones/e0504.html and specifically here: http://www.nielsengallery.com/db/CharlesJones/longpod.html His process is described as "gold-toned silver gelatin" and I know he worked on glass plates. Is anyone doing any work like his these days? I've looked around online and met with no good results. I've seen other people doing gold-toned silver gelatin but it never looked like his. How would one go about reproducing the effect these days? Any good tips?
