<p>[QUOTE=&quot;SuperDave, post: 2429096, member: 1892&quot;]That&#039;s an artifact of the structure and process of a scanner. They employ a line-form light passing over the subject - the whole width of the scanner surface is covered by a single &quot;bulb&quot; passing over the surface to be scanned, and the resulting image is not a point in time but a <b>compsite</b> of what amounts to a timelapse exposure where every aspect of the subject is only shown in its&#039; optimally-lighted state. That &quot;optimal&quot; is defined by the scanning software, which is why two different scanners of similar resolution specs can return entirely different results when (mis-employed) used to scan something like a coin which covers only a small percentage of the scanned surface. They&#039;re more detail-accurate than most photographic images as a result, but not necessarily accurate for the subjective evaluation of surface&nbsp; since they&#039;re the equivalent of a planned, staged photo shoot.[/QUOTE]</p><p><br /></p>
