I've heard some talk on this board about the accuracy of film holders and I am t alking to a tool and die maker about making a device to more conveniently measur e the film holder outer flange/back, film plane area of the holders. Does anyone know, for sure,what this distance it?....and is the ANSI spec sheet...#ANSI/PIM A IT3.108-1998? Thanks in advance for any help. Richard Boulware - Denver.
