<p>[QUOTE=&quot;expat, post: 8145019, member: 111067&quot;]Imaging coins in slabs especially, is difficult. The slab is nearest the lens so the focusing is prioritized on the nearest point. Lighting is most important, so experiment with brightness and distances and try to eliminate all other ambient lighting. With a smartphone supported correctly and distanced so the coin fills the viewing screen without using the zoom, images should be much clearer. With raw coins the subject should be raised from the background allowing all the focusing to be on the coin and not on the background. Setting the timer to 2 seconds takes away the problem of camera shake at the crucial moment. Experiment also with different background colors for different coin compositions. Solid white, gray or black for example. When saved then crop all un-necessary background leaving only the coin. A standard image of the slab for label info is sufficient. </p><p>As always, experimentation is the key.</p><p>Processing software becomes almost redundant if you get the white balance and focusing correct[/QUOTE]</p><p><br /></p>
