<p>[QUOTE=&quot;RonSanderson, post: 2799407, member: 77413&quot;]I originally used a gray card to set the white balance, but the whole operation is appallingly seat-of-the-pants.</p><p><br /></p><p>I don&#039;t have an official gray card so I don&#039;t trust my makeshift one to be either neutral gray or 18%.</p><p><br /></p><p>As for exposure, I only have in-camera metering.[ATTACH=full]652292[/ATTACH]The video feed of my old Sony is meant for showing slideshows on a TV. If you patch it into a monitor it gives an ersatz live view capability. This is where I get my exposure reading - shown as the last of the four readings across the bottom.</p><p><br /></p><p>I can&#039;t fill the sensor with the image; I can&#039;t see the coin in focus; white balance is a guess; and I set exposure by eye by comparing the blurry screen image to the coin under the lights.

I check color accuracy by sending the final image to my iPhone to check it there.</p><p><br /></p><p>I hope this sorta wanders by the vicinity of an answer.
