I don't know if many of you follow the <http://www.luminous-landscape.com/> web site. The owner, Michael Reichmann finances the site by selling DVDs.
The current DVD (#14) has a fairly long segment that contains a tour of Butcher's darkroom and a walk-a-long on a shoot in a swamp. Butcher makes some seriously large prints. He called a 3 foot by 5 foot print "one of the smaller prints". A single DVD is about $20. There is a bit of a discount for annual subscriptions. This isn't intended to sound like a commercial pitch. I don't have anything to do with the site or it's owner. I find the videos informative and entertaining. See you later, gs <http://www.georgesphotos.net>
