[QUOTE="Denis Richard, post: 4607591, member: 112673"]Speaking of cutting a coin out of the background, I went to the NGC page this morning to look at their Photo Vision raw coin imaging service (and compare pricing) and I was surprised to see their "quality" example image wasn't well cut out. Here's the full size image, right from the site: [ATTACH=full]1141251[/ATTACH] and an enlargement of the coin cut out, between the coins. [ATTACH=full]1141252[/ATTACH] On the right coin you can see how they have made straight slices around the edge, rather than follow the actual dings and dents of the coin, and on both coins there is a halo from inaccurate selection and no feathering. This is evident all around the perimeter. On the bright side, seeing into the dent does indicate they shoot these on a white background before they cut them out. Personally, I think that is critical to illuminate the edges of the coin.[I] [/I]I realize the "white" background here appears greyish, but that's because it’s underexposed.
