thanks so much for all this info. I'm going to try the paper shooting - and the apug member here that sold me some film holders pre-loaded a few with some cheaper film for me to start out too- very kind of him. The lens is a bit controversial I guess. (some say it will cover just what I need some say not....) I had one that was too long and so I have that put away and now I have another but it just covers the 8x10 (according to the seller on the lg. format forum)....guess testing it will prove. I wanted a 12" 300 but couldn't find one in my price range so this one isn't it. this is a wollensak 9 1/2" in a no.4 betax shutter. my 8x10 is at least 100 years old now but I look forward to using it as much as I can. thanks for the exposure info too TheFlyingCamera.
