By the way I purchased your book and DVD's - I'm Hooked! I first developed film and enlarged photos in 1970. In 2010 I purchased a Crown Graphic on Ebay and rejoined the hobby. I really missed the hobby for all of those years. As a Chemical Engineer the topic of VAg and the science behind it is interesting. I have found several patents, applications and papers from RIT that describe the process. I have also read all of your posts on this site. I have even obtained the Computer programs Kodak once used to control the reaction - fascinating stuff.
I hope to make the August Workshop. My wife suggested it as a Christmas gift.
