A really great photographer who choose color and defined the West coast style in color. I have seen his photographs in Carmel and they are absolutely beautiful. He had a large part, with Brett Weston, in the development of Edward Weston in completing his life's work under his direction. A difficult project when you consider someone is printing your work being your hands. It's not just anyone who would devote so much time to another's work.
Since a workshop is not available with him, I suggest you get the Daybooks of Edward Weston, The DVD; "The Photographer" with Edward Weston and the DVD of Brett Weston. Read these and go on the web to get great information and education.
