Well, I wonder what is the easy way to get the knowledge from workshops you are talking about in my case - guy living in Europe.
I suspect there are lots of great workshops in London, i'm thinking Rudman, Waite, Cornish (more d.g.t.l), Ephraums (if he still does them). When i was in death valley with Barnbaum, there was a fellow from Austria having a great time photographing and enjoying the American West. Where there is a will, there is a way.
