I saw your earlier shot, but didn't have time to comment then. I recall liking the lighting better on the prior shot---really liked the effect of a "ring" of highlights around the edge of each raised surface as well as the edge of the coin. Each of the edges has a "harder" look now, probably due in part to your more aggressive use of PP. ---Chris
Thanks to Jason for critique of previous effort at this subject. Took a new shot with tripod/self-timer to get sharp as possible. Played around with contrast/hue/USM. Hopefully this has a bit more 'bite'?
