<p>[QUOTE=&quot;dougsmit, post: 3270870, member: 19463&quot;]The photos are great but you can use a small aperture to increase depth of field as mentioned by others above.&nbsp; There is a problem with overall sharpness limitation by diffraction when you stop down too far so it is bad to shoot everything at f/16-22 unless needed.&nbsp; The other answer is to use photo stacking software where you take several shots each focused on a different plane and let the software combine them into one using the sharpest part of each.&nbsp; For coins, three input images may be enough but I have shot flowers using ten and microscope workers use many more.&nbsp;&nbsp; This allows tilting and dealing with high relief coins. </p><p>Samples:</p><p>[ATTACH=full]862661[/ATTACH] [ATTACH=full]862662[/ATTACH] [ATTACH=full]862663[/ATTACH] [ATTACH=full]862664[/ATTACH] </p><p><img src="http://www.pbase.com/dougsmit/image/111130430.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p>I use a freeware program called CombineZ but there are many others I have not tried.&nbsp; I do not collect software and CombinesZ has been all I need. </p><p><a href="https://en.wikipedia.org/wiki/CombineZ" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/CombineZ" rel="nofollow">https://en.wikipedia.org/wiki/CombineZ</a></p><p><br /></p><p>I first used it for flowers.</p><p><img src="http://www.pbase.com/dougsmit/image/60309583.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
