Hello: I know some of you will tell me to just experiment, but I am wondering if there is a way to estimate how close/far to be with a pinhole camera of a given format and focal length to estimate composition? Or do we all just develop a realtionship with a particular camera from experience?
With my 35 mm pinhole, I used the meter on the converted camera, and pre-viewed my composition thru another SLR with the zoom set to approximate the f.l. of the 35 mm pinhole camera. I'm just not confortable 'blindly' pointing and shooting and hoping I'm not too close, not too far. Can an analogy be drawn between a 'normal' perspective focal length on two different formats? Say, a 50 mm f.l. lens on a 35 mm camera is about the same (whatever same means) as an 85 mm lens on a 120 / 2-1/4" camera. I saw a pinhole camera on the Internet somewhere (Australia?) that had a wireframe 'viewfinder' on top and side. I guessed the manufacturer figured out how big to make the rectangular 'viewfinders' by trial and error. Thanks Murray
