Thanks, Sidney -- always a treat to share here!
As far as photo setup goes, I am using an 85mm 2.8D PC-E lens on the Nikon D700 (I have a D800E on order, which I'm hoping will enable another level of clarity!). The first two shots in the post were taken as single exposures (the PC-E obviously helps a lot here) -- the other group photos were taken using multiple exposures, focus stacked with Helicon Focus, and then post-processed in Photoshop CS5. I use a light tent with standing dome lights (no flash) to play with lighting angles and contrast, and a remote shutter release. Tripod and head are heavy Manfrotto items to reduce any shake on the camera. Finally, I do zone in my lenses using LensAlign PRO to help the AF precision on my other lenses (like the 105 2.8 Micro) -- of course, I am focusing the PC-E manually.
Hope that is of some interest!
Best,
Gary
