Hey there. I'm using a sinar 4x5 camera with a 210 mounted on a flat lensboard. When using a depth of field chart like: http://www.rbarkerphoto.com/DOF2.html where does one measure from? For example, if using a tape measure, should I have the starting point (zero) be the front of the lens (i.e. the UV filter on the lens), the lensboard, or maybe (though I couldn't see why) the film plane?
Thanks,
Serge
