Cor, I am trying to understand your question, but I am having trouble figuring out how your Palm software comes up with a bellows factor of 3.2. Among many other useful identities discussed above, Bellows Factor = (1+ Magnification)^2. So a Bellows Factor of 3.2 means the Magnification is 0.79x. That implies that the field of your head & shoulders portrait is an awfully tight 9.8 inches by 12.4 inches. Is that the kind of cropping you are looking for? What did you enter into the Palm that it used to determine magnification or field size? Thanks
