[QUOTE="justafarmer, post: 2288345, member: 3926"][ATTACH=full]458522[/ATTACH] [ATTACH=full]458521[/ATTACH] I borrowed your image from your post to illustrate a question I have. Hope you don't mind. Scanners do not scan perfect. The scanner head never comes from the factory set perfectly square to the scanner bed. They all scan at a angled perspective. Refer to the crude arrows black and yellow I drew on the image above to illustrate this point. What a flatbed scanner will do is scan imperfect - perfectly each time. If this makes any sense. Always at the same focal length, distance and angle to the scanner bed. If you put your coin in a 2 x 2 cardboard flip, which are cut almost perfectly square, square the flip edge against the alignment bar on the scanner and make 4 different scan rotating the coin 90 degrees each time as illustrated in the image above. You capture 4 different perspectives of the coin at the same distance, focal and angle. Import the 4 scans into your image editor rotate right side up and stack and render them into a 3-D image. Do you think this would work?[/QUOTE]
