<p>[QUOTE=&quot;dougsmit, post: 4644275, member: 19463&quot;]Usually I combine the two sides of a coin before posting but I decided to try and see if the CT limit would take a single from the camera.&nbsp; The answer is no.&nbsp;&nbsp; This file was 4160 pixels wide out of camera but showed up on CT at 1920 pixels reduced by CT software without notice.&nbsp; When I tried uploading a joined pair, I got an error message so the limit is somewhere in this range.&nbsp; I was hoping to show the details needed for big prints.&nbsp; As is, click to see the reduction and note the red thread in the eye from the tray in which the coin was resting.&nbsp; Memo: dust coins before shooting.</p><p>[ATTACH=full]1147607[/ATTACH]</p><p><br /></p><p>Never being one to let well enough alone: the file was uploaded to Google drive and viewing allowed by anyone with the link.&nbsp; I do not know what it will look like or if all can view it but would appreciate hearing if anyone cares to look.</p><p><a href="https://drive.google.com/file/d/1lEOSDahR7L290NT2KRmWM62XSVloF_2m/view?usp=sharing" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://drive.google.com/file/d/1lEOSDahR7L290NT2KRmWM62XSVloF_2m/view?usp=sharing" rel="nofollow">https://drive.google.com/file/d/1lEOSDahR7L290NT2KRmWM62XSVloF_2m/view?usp=sharing</a></p><p>At this size, the depth of field at f/11 shows a difference between parts of the eye and nose.&nbsp; I avoid shooting smaller apertures than f/11 to avoid diffraction which lowers overall sharpness.&nbsp; Also, this was saved as a level 7 compression JPG so that may be limiting detail.&nbsp; I see more testing coming.</p><p><br /></p><p><a href="https://drive.google.com/file/d/1fH4YwzkDtap0H__dnNWSWfKWprxyjoUI/view?usp=sharing" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://drive.google.com/file/d/1fH4YwzkDtap0H__dnNWSWfKWprxyjoUI/view?usp=sharing" rel="nofollow">https://drive.google.com/file/d/1fH4YwzkDtap0H__dnNWSWfKWprxyjoUI/view?usp=sharing</a></p><p>The above is the reverse as a level 12 JPG cropped to 4160 pixels square.&nbsp; The question is whether the much larger file size here added any noticeable detail compared to the compressed obverse.&nbsp; I believe this demonstrates &#039;overkill&#039; but even this size only supports 300 ppi up to about 14&quot; so, in theory, it would show &#039;problems&#039; on a poster if you looked closely enough.&nbsp; What we have to ask is whether we need posters of our coins.[/QUOTE]</p><p><br /></p>
