So I have four pinhole type cameras in my experimental setup. All of them have the same magnification and are placed at the same distance away at different locations except one which has a different magnification and zoom. This camera is 72.5% further and has 52.5% less magnification as the rest of the cameras. The magnification problem could be worked out in a photoshop by an appropriate 52.5% zoom (or so I naively assume) but how to correctly zoom to adjust the difference due to position seems to be a harder problem. I am only familiar with the lens-makers equation to tie in magnification levels with image distances etc, but a pinhole is not a lens and I am not sure how to fix the distance problem with zoom. Any ideas? I'd like to calibrate all of the cameras. Thanks
