<p>[QUOTE=&quot;SuperDave, post: 2361626, member: 1892&quot;]That is a percentage of the axial lighting process. The part you&#039;re missing is that any direct illumination of the coin has to be blocked - all light has to reflect from the glass down to the coin - and the angle needs to be ~45 degrees. Further, it&#039;s a really difficult technique to master and is only advantageous for toners as it seriously compromises exposure and ISO since so little light hits the coin.[/QUOTE]</p><p><br /></p>
