Re: Alignment problems

One of the problems that I have found in stopping down a lens to try to get a larger depth of field is that that introduces refractive error that David doesn't seem to compensate for. As per our discussion off line, I did some tests today with a setup calibrated to 200mm panels. Your assertion seem...

Adjusrting camera aperture during scan session

Does anyone change the aperture during scans here? Here's the video: https://www....
