<p>[QUOTE=&quot;RonSanderson, post: 2823255, member: 77413&quot;]Brilliant silver coins are not easy to photograph. Their high bright-white brilliance causes problems with camera exposure.</p><p><br /></p><p>The photographer can try to capture the brilliance but the brightest spots will be overexposed. Or the photographer can underexpose the image so the brightest spots retain details, but then the rest of the image is too dark, giving the coin an unnaturally dark appearance.</p><p><br /></p><p>The image here tries to keep the bright appearance. This coin is a dazzling blast white.</p><p>[ATTACH=full]663402[/ATTACH]</p><p>Most of the coin is well rendered. The area above the ear, below the wing, and at the back of the neck have been overexposed to a solid white. The exposure could be shortened to keep from blowing out these details, but the tradeoff is darkening everything else.</p><p><br /></p><p>An animation can help in two ways. As discussed in this thread, rotating the coin through several photos will demonstrate how the luster moves around the coin.</p><p><br /></p><p>Second, each lighting angle give the coin a different shape under the lights. A point that is overwhelmingly bright in one frame will have different lighting in the next. This means the photos can be brighter - what is lost in one frame will reappear in the next.</p><p><br /></p><p>This animation includes the image shown above. The details lost in that frame are compensated for in the others.</p><p><br /></p><p>Animation may be the key to portraying brilliant coins.</p><p>[ATTACH=full]663400[/ATTACH][/QUOTE]</p><p><br /></p>
