<p>[QUOTE=&quot;drathbun, post: 1934376, member: 42789&quot;]You&#039;re on a tripod. Shutter speed should not matter. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>The aperture f-16 should give you the best quality image. I would suggest that you use it, set the ISO to the best possible quality your camera supports, and let the shutter speed float to whatever it needs to be for that particular aperture / ISO combination. Or better yet, get a proper shutter speed by exposing a gray card and then set everything manually so that your camera doesn&#039;t try to &quot;Fake you out&quot; by adjusting something on the fly that you&#039;re not aware of.</p><p><br /></p><p>If the lighting is right, the focal length is consistent, and basically everything else is the same, then every exposure should be exactly the same. Otherwise the camera will try to bring lighter-colored coins down and bring darker-colored coins up in the exposure, as the logic in the camera is designed to skew towards the middle (gray) colors.[/QUOTE]</p><p><br /></p>
