So I just took a chance on a old Speed Graphic on the big auction site, and it should be arriving any day now. Either I've been watching too many old movies with scenes of hordes of news photgraphers and their big press cameras, or the ghost of Arthur Fellig came to me in a dream, I don't know. What I need to know is there a good book or other source of information that would cover some of the basic issues of large format--things like how to load a film holder, when to use movements, and that sort of thing. Some things are not real obvious, at least not to me--after you've made your exposure, do yoou leave the film in the holder until you get back to the darkroom? What if you have color film you want to send to a lab? so many little details.
