Images taken in a controlled environment or with a posed subject. All subject types.
This is a small specimen - 14 mm across at the top - of gemmy aquamarine from Erongo, Namibia. This is probably the single image I'm most proud of to date.
D7000 on custom stepper controlled closed-loop sled, mounted on tripod, angled to view specimen from above which rested on a borosilicate glass plate with black velvet backdrop and diffuse continuous LED lighting from above. Stacked with Zerene Stacker (DMap).
I use an oddball lens, the Nikon 70-180mm macro, which for this was set to maximum magnification at 180mm which is 1:1.3, and functionally becomes 1:1 with the Nikon 6T closeup lens attached. The 70-180mm macro is really convenient for mineral photography as it does not focus breathe or change its effective aperture as it is focused down.
