Hello,
I hope I put my query in the right category.

In 2015 the Japanese photographer Chieko Shiraishi published his book "Shimakage (Island Shadow)". The images of the book are gelatin sliver prints which have been processed under an old Japanese retouching technique like "rag wiping", named "Zokin-Gake". I tried to find more info on this process, but nothing found. Is it a bleaching technique? Any text or tutorial on how to do it? In fact, my knowledge on any bleaching technique is quite limited.
Thanx in advance,
Fotis
