After reading multiple posts here and spending about six months of research I bit the bullet and picked up an Ebody RW45. I'm overwhelmed by the quality of the camera (my previous LF was an Omega-View monorail which lacked the finer points of precision). Question is - what's the right way to zero out a 4x5? By this I mean the front lens board is slightly offset (the lens is mounted off-center towards the bottom of the square). So what is the "zero" position, where the center of the lens strikes the center of film? I guess I'm asking (a) does it matter - I tend to compose with my eyes and not with a ruler and calculator and (b) if it does matter, what's the right way to establish the position? The Ebony has indents for zeroing everything except the lens (for the obvious reason that the lens can be mounted in a different position depending on the lens/board combination). Thanks in advance. I fired off a few shots and am just amazed; the super symmar apo i picked up with the Ebony really blows the old angulon I have on the monorail away.
