<p>[QUOTE="messydesk, post: 4862706, member: 1765"]I'm surprised I just ran across this thread today. Lots of interesting points made here. With no big shows since FUN, my professional coin photography biz has screeched to a halt. The only shots I've taken lately have been my own. I'll comment on a bunch of stuff I've seen here all at once.</p><p><br /></p><p>My setup is a Nikon D610, usually with a 200 mm macro, sometimes with a 105 mm (larger objects and slabs), or even a 55 mm macro (much larger objects). Since almost everything I shoot is slabbed, axial lighting is not useful for me. The closest I've come to something like it is my makeshift white paper shroud crammed onto the end of my lens with the lights pointed at it. The built-in lens hood of the 105/4 Micro-Nikkor keeps that lens from flaring, and the 200/4 just doesn't flare.</p><p><br /></p><p>Regarding whether or not post-processing is not photography, so what? If you have an end-product in mind that's not possible to capture with the camera, post-processing is just another tool in the chain that is used to produced your finished product.

It's bad for two reasons -- you can tell it's too much, and it doesn't look like the coin. Of course, you can "juice" a picture without post-processing by setting the saturation too high on your camera. Same result, different toolset. Do I do off-camera exposure, highlight, shadow, and saturation adjustment? Absolutely! Can you tell where I did it? Probably not. Does it look like the coin? Yes.
