Ok, a real newbie question here. I have been shooting film for quite some time, 35mm as well as medium format, but I have yet to fire the shutter on one sheet of large format film. I am trying to step into this very gently, spending as little money as possible until I decide whether I like this type of photography or not. So I need some advice from those who have been here before me. I recently picked up a very nice Calumet Cambo 4x5 camera with a 150mm Schneider Krueznach Synar in a Copal #1 shutter and a Graflock back. I have picked up two Toyo film holders and a package of Arista Edu 100 b&w film. I have a very capable tripod, leveling base and heavy duty ball head from my medium format work, as well as a good shutter release cable and a spotmeter. I think I am ready to go out and give this a try but I realized I have no dark cloth. Not much call for those in my medium format work. Is this an important item or, is it something I can do without while I am trying this out. If you believe I need one what should I look for. I want to stay thrifty but I do realize that having decent equipment is an important part of the experience. If there is something else I may be missing I would appreciate your thoughts on those items as well. Thanks in advance.
