Camera extension was actually a curse for the Weyba Bridge #5 exposure. What I needed was strong bellows compression to get a 121mm lens close enough to the film to get infinity focus. To do this I had to unhook the lens board from the vertical guides of the front standard, shove it backwards, then lock it down so it was centred and parallel to the ground glass. Checking image coverage involved walking back and forth to look at the ground glass through the lens and to look at the lens past the corner of the ground glass. Even for view camera work this was a slow procees. Fortunately the subject wasn't going to die, deteriorate, or run away inside ten minutes.
