Just wanted to check on bellows extension effects on exposure. I haven't worried too much about this as much of what I have shot has been at near infinitiy settings, and when using an RB67, there was a wonderful little scale on the side of the bellows if I racked out far enough to need to worry about it. However as I get ready for my new Wehman 8x10, I am wondering about significant movements affecting exposure through contorted belows distances.
I understand that the focal length of the lens establishes a baseline for image brightness. And that when I reach half again that distance I need to increase by half a stop, twice that distance a full stop, etc. This camera has base tilt in front and rear and fairly significant rise. Besides bracketing, is there a way to handle this quantitatively or are the effects of movement not significant enought to worry about?
Thanks
Stew
