<p>[QUOTE=&quot;RonSanderson, post: 2593039, member: 77413&quot;]So much information, and so little ability to express thanks. I have a lot to think about and to try.</p><p><br /></p><p>You have already given me an idea to try. Right now the Jansjo lights are in a high axial position. The light hits all surfaces of the coin evenly. I have this idea.</p><p><br /></p><p>If I lower the incident angle of the lights, can I use shadowing to show the contours, instead of relying on just the contrast inherent to the coin?</p><p>[ATTACH=full]564824[/ATTACH]</p><p>On this diagram, the blue line represents the surface of the coin. At A, the light source shown by the green arrow would brightly light the left part of the contour, while the right light (red arrow) would strike a glancing blow. The center, B, shows a flat area receiving equal light from both sides, and the right arrows, at C, show illumination mostly from the right. So there would be gradations in the light that may show the detail even on an uniformly colored coin.</p><p><br /></p><p>So I plan to try a low angle, possibly in conjunction with a very close macro distance. The light could still come in under the edges of the lens, while direct overhead light would be blocked by the camera, adding to the shadowing effect.</p><p><br /></p><p>Another idea is to use a broader light source. I posted a photo of a 1936 Mercury the other day (see thumbnail) which I took using only the 4 foot daylight fluorescent over my workbench. It created a beautiful diffuse lighting. So that may also work to give a nice light variation over the contours.</p><p>[ATTACH]564825[/ATTACH]</p><p><br /></p><p>So much to try! Thanks to both you and Bob! I will try to post any successes, assuming there are some.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie59" alt=":joyful:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
