<p>[QUOTE=&quot;messydesk, post: 2425883, member: 1765&quot;]There is a limitation to this approach, however, in that whenever you look at a coin, you tilt it around in the light.&nbsp; An HDR 2D image may be the basis for the color information, but not surface or luster quality.&nbsp; Being able to move the light around in viewing is equivalent to tilting the coin, assuming stuff like luster plays nice with this technology.</p><p><br /></p><p><br /></p><p>Where I see an interesting combination possible is combining this with focus stacking so that you can use this for &quot;virtual microscopy&quot;.&nbsp; You&#039;d need a lot more pictures at every plane, to capture the surface normal characteristics accurately for all the in-focus pixels, but then you&#039;d have more accurate 3D information and also be able to move the object in addition to the light.&nbsp; With the 3D information, you can also re-focus the image at viewing time, but you&#039;d need that built into the viewing software, of course.[/QUOTE]</p><p><br /></p>
