<p>[QUOTE="Denis Richard, post: 24850466, member: 112673"]You can shoot a mirrored coin straight down and not see the camera if you're using axial lighting. To demonstrate, I found the image below on eBay, and it illustrates the perils of shooting a mirror finish coin straight down in regular light. You can see the reflected skin tones of the hand of the guy who took the picture. </p><p><br /></p><p>[ATTACH=full]1592526[/ATTACH]</p><p><br /></p><p>The secret is it's not about moving the camera, tilting the coin, or moving the lights because photographers don't light a mirror, they light what it is reflecting, and that should inform your lighting and camera placement decisions. If you photographed a mirror on a wall, the only light you'd see hitting it would be on the mirror frame, the rest would bounce away. If you were in a dark room the mirror in the photograph would be black. You have to light what the mirror is reflecting to make the image work. Same thing with a mirror coin. For this reason, I often place a white card in the path of the coin reflection to add texture and a gradient across its surface.</p><p><br /></p><p>Below are two angles of the same left coin as in the eBay photo above.[ATTACH=full]1592527[/ATTACH]</p><p>This one is straight down with axial lighting and next is the rest of the set.</p><p><br /></p><p>[ATTACH=full]1592536[/ATTACH] </p><p><br /></p><p>The image below is also shot straight down (without axial lighting) but the coin is slightly angled.
