I currently use a 20x24 box type camera fixed at infinity focus with a Goerz 30" Artar which I love but the near focus distance is 20' at f128 so I've been limi ted to shots off bridges or overlooks etc. I wish to build a second box camera using this lens which will give me a focus range of say 6' to 300'. I've attemp ted to run the calculations and figure if I move the lens out 4" to a total 34" from the film plane and tilt it downward 10 degrees i.e. the Scheimpflug Effect, that this will give me the desired DOF. Can anyone confirm these calcs or stee r me in the right direction?
