That is good news on the LF forum. With the switch to photonet it lost a number of long standing contributors and a more congenial, collegiate feel. At the LF photography web site is where it belongs.
David is correct about the locations, although I believe that one of the cameras is sometimes transported to different locations for various events.
There was a pretty in depth article in View Camera a couple of years ago, about Tracey and others who run the camera. If I remember anyone can schedule a time to use it, and that includes technicians to help with lighting and the camera operation. I don't know if the article mentioned the cost, but the number $200 an hour seems to stick in my head and I believe that incuded materials.
David, perhaps you know the amount and details better then I can recall.
