These photos were taken on my father's Nikon D100 with a 60mm f/2.8D AF Micro-Nikkor lens, on a Gitzo G2227 tripod and an Arca-Swiss B1 monoball. The lighting was a cheap Ikea halogen lamp with a blue shade (which can be seen in reflection on the Mini Mag-lite photo).
All photos were taken at the D100's lowest ISO setting of 200. CFn24 Mirror shake reduction (mirror lock prefire) was used. The first two photos were taken using AF in Single focus mode, the other three were focused manually. Keep in mind macro lenses have very little depth of field.
The first photo was taken with automatic white balance, all others used a custom white balance preset on a Delta 1/CPM 18% gray card (which is also used as the background for the last 3 photos). On my color calibrated monitor, all but the first photo have a truly neutral gray background.
Images were converted from compressed NEF (RAW) format using Photoshop 7 and the Nikon NEF plug-in, converted to 8 bit mode, converted from the AdobeRGB 1998 color space to the sRGB color space (using Adobe ACE Perceptual intent and no dithering), and saved to JPEG format using quality 10. No sharpening or other corrections were applied to the images.
