<p>[QUOTE=&quot;Ordinary Fool, post: 2666212, member: 85318&quot;]I don&#039;t know much about anything other than I can look at or photograph a coin in high-quality mono view and errors show that don&#039;t or aren&#039;t as pronounced under quality stereo inspection, seldom vice versa.</p><p><br /></p><p>If I were using your device to photograph coins, that I am pretty sure lends itself well to photographing a series of the same shots with having a focal point somewhere around 0.001 to 0.003&quot; from each other in a progression. Then you can take the jpgs, tifs, pngs or whatever it churns out and lay them on top of each other and generally, the result is a large photo-file having much better detail. You can tinker with the &#039;transparency&#039; when layering and often to good effect. </p><p><br /></p><p>Microscopes for that specific purpose have micrometric click stops on the focus knobs, similar to the fine click adjustments on some ol Lyman, or any number of manufactured rifle sights.</p><p><br /></p><p>To make do, you can put a dial indicator in the mix and zero it. Then go at it but, it is tedious, especially if you are not just doing 5 layers, but 20.</p><p><br /></p><p>This can also be done in stereo using R and L eyepieces of a stereo optical device. </p><p><br /></p><p>With a mono device, offsetting the subject R and L a very specific calculated distance from the dead center 0,0 coordinate on the X axis can produce simulated, not true, stereo results unless you change the angle of the line of sight of your scope off vertical, for right and left. That is quite complex since you must also move the subject too. It is also subject to high probability errors since the process is tedious. The QA verifying accuracy is beyond the scope or ability for quite a few mammals that might wish to try it.</p><p><br /></p><p>Does any of this make sense?</p><p><br /></p><p>I have one of those 2009 Lincolns that using various devices/lighting for visual inspection or photography, his fish lips (different than what your curious coin presents) can look like a crazy error, possibly variety, or PMD.</p><p><br /></p><p>Have you seen that lincoln professional years coin where his mouth looks much like fish lips?</p><p><br /></p><p>It is nice enough that one day I&#039;ll shoot it as described in stereo and stack all the images hopefully for a very lifelike digital rendering.</p><p><br /></p><p>I&#039;m behind the curtain with ms. piggy.[/QUOTE]</p><p><br /></p>
