Really nice Nickel and photos. What are the light positions?
Clock positions Height above coin Angle vs horizontal
You seem to have nailed a good position to have excellent shadow and surface detail.
But you need to rotate the reverse a bit clockwise...Ray

That was from a genuine unsearched roll... they are all toners. There were maybe 15 gems and this is one of the nicer ones. Thanks.
As for lighting...
I would say one and 5 oclock
diffused with something like your smile diffusers
the heads were slightly angled to place the lights as near to right above the coin as possible and only say 3 inches above coin
It was a bit difficult to give this coin enough soft light to show the toning yet show a bit of the blazing luster.
taken with a 70mm Sigma DG EX Macro (extremely sharp lens) F9, 1/30th sec
Oops.. I linked to a coin that I had not rotated... :)

@ rmpsrpms, I said this elsewhere but I appreciate your work here as a former fine-art and commercial photographer. Your imaging is stunning. Thanks for the inspiration.

Wow, thank you very much dgleich. It's taken a lot of work to get all the elements lined up. Key has been the Jansjo lamps and I'm amazed that a $10 item has such an impact on the outcome of my photos.

No problem, it is quite amazing that you can buy these accurate color temp lights for such a small price. I looked around a year and a half ago to find small consistent low heat lights but found nothing under $150 each. Photographing coins with my strobes was not an option!
My macro lens is one of the sharpest ever made but wish it was a bit longer. I will be looking for a bellows and trying to find the Schneider 135MM APO Componon S that I never sold. I have it somewhere... Too bad I sold my 135mm sironar s large format lens... I bet that would have worked well as it was the sharpest lens I have ever seen. There are many options out there if you can adapt them.

dgleich, just wondering what kind of Camera body are you shooting with? Full frame? I have found 135mm to be too long a focal length for the APS-C sensor size for capturing full-coin images (working distance is beyond the capabilities of my copy stand extension). Ray recommends between 75mm and 105mm lenses for full-coin images with an APS-C size sensor. If my math is correct, that would be about equivalent to roughly 105mm to 160mm for full-frame. At least, I think so...my brain may be thinking in reverse about this...it is Friday after all  .

If it is a Sony A-100, with an APS-C sensor, you will have to be about 22" above the nickel to fit it on the sensor with a 135mm lens. My copy stand only lets me go to about 18" extension, and I can get a little extra from the dovetail bellows rail. But, for a silver dollar, I'd have to be about 26" or 27" above which I can't physically do with my set-up. If you have a very tall copy stand extension you're golden, as long as it's very stable.

As the lens gets longer, both the distances from the lens to coin as well as lens to camera increase, so you get a double-whammy. I have a few 120mm, 135mm and 150mm lenses that I simply can't use with my setup because my stands (even the big, cheap Chinese one) just won't go high enough. Plus, the RANGE of extensions and working distances between Dollar and Cent or worse Dime shots is increased with longer lenses, so any stand you work with will need to have a wider adjustment range. This is why I have settled on the 75-105mm range. 75mm is on the edge of being able to achieve 0.4:1 for Dollar shots (minimum bellows extension limit), and 105mm is on the edge of being able to get enough copy stand extension for full-frame focusing (with my stands)...Ray

Yes... that is the camera I used. I am actually working with a commercial floor standing camera stand over a table. (solid enough for large format) A copy stand would be better... but priorities, priorities. I was always a big German glass guy... Rollie, Contax and large format. All of my lenses are gone except for the one Schneider. I can see the 135mm not being ideal but would still like to see the sharpness.
I actually bought into Sony due to them announcing Zeiss lens'. Nikon has them now of course and it turns out, Canon can adapt ALL of the amazing Contax Carl Zeiss lenses. The best Macro lens ever made is the Carl Zeiss 100mm F1.2 IMO.
I like the bellows setup though as I am very used to that being a large format photographer... former LF photographer I should say.
I also have debated about switching systems but will likely go with a new Sony as they finally have again included basic things like depth of field preview in newer apc cameras. I would like to go full frame but am hesitant due to having some great lenses that only cover APC.
Sony's 16MP sensor, that is used by Nikon and Pentax as well seems incredible... any real world thoughts? The newer 20+MP sensor looks good as well but only up to 200 iso.

Wanted to print 16*20 with an 8*10 enlarger. Our whiz-kid simply ran the enlarger off the top of the pole, turned it around, and projected it on the floor.
