Title: RE: copper prints was: Anyone doing autochrome?

Charles,

I worked a bit on copper printing,after Judy showed me a promising article on it by Chris Patton. I wrote my results up for Post Factory. Chris Patton has a web asite up at: http://pinhole.stanford.edu/cp.htm, and he has also some info on my results at: http://silverghost.stanford.edu/copper/index.html

Good luck,

Best,

Cor

I would love to know Bernie's formula/method and any other copper method.
