<p>[QUOTE=&quot;rmpsrpms, post: 26057971, member: 31773&quot;]My setup has evolved quite a bit since this thread went cold a couple years ago. I&#039;m now using a Sony A7Rm4 and have shifted over to a stacking setup based on a microscope focus block. I built this system for higher magnification use to do phono stylus imaging, but eventually found that it was flexible enough for coin variety use, and then for full-coin use, and most recently for imaging of record grooves. So it is my primary system now, replacing the older ones based on linear rail stacking. I posted a thread back in Apr &#039;22 showing the system, and it still looks pretty much the same today:</p><p><br /></p><p><a href="https://www.photomacrography.net/forum/viewtopic.php?f=25&amp;t=44877" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.photomacrography.net/forum/viewtopic.php?f=25&amp;t=44877" rel="nofollow">https://www.photomacrography.net/forum/viewtopic.php?f=25&amp;t=44877</a></p><p><br /></p><p>I was still flummoxed by the discussion of RAW, but I do finally understand what is going on. My concern was always that folks claimed highlights and shadows were recoverable with RAW, but of course this is physically impossible. However, after some discussions, it became clear that those who make the claim are actually shooting with reduced exposure, ie &quot;Exposing To The Left&quot;, or ETTL. I surmised this earlier in the thread, but the wild claims of recovery didn&#039;t seem to include such under-exposure. Time and experience has shown that indeed it must be the case, and that ETTL is the explanation. Of course shadows are lost with this method since there are only so many bits of information available, but there is the benefit of shorter exposure times, so perhaps that balances out. For me, I still prefer ETTR, with compensation to avoid over-exposure, but at least I understand what&#039;s going on with RAW now.</p><p><br /></p><p>I&#039;ve added a few more Hi-Res photos to my online library, but am still very slow to flesh-out a broader offering since I have to host these via 3rd party. I do plan eventually to update my website to include a large zoom viewer, but til then I continue to use EasyZoom for these. Here is a recent image of a 1950-D RPM-003 that I traded for. Tough coin to find, so I decided to shoot it in Hi-Res for folks to have a complete reference for the variety:</p><p><br /></p><p><a href="https://easyzoom.com/image/581867/album/0/4?mode=manage" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://easyzoom.com/image/581867/album/0/4?mode=manage" rel="nofollow">https://easyzoom.com/image/581867/album/0/4?mode=manage</a>[/QUOTE]</p><p><br /></p>
