Hello, I'm conducting two wet plate Collodion workshops this Spring/Summer - one is May 27th & 28th and the other is June 3rd & 4th. You can read about them here. Also, if you are interested in trying wet plate but don't want to spend the time or money on mixing raw chemicals, visit AltPhoto Source and get all of the chemistry (and most of the supplies) you need to make wet plate images. The address is http://www.altphotosource.com. Thanks!
