A Nikon D3x on a camera stand with strobe lights was used. The camera was tethered using NkRemote software. Focus stacking software used was either Helicon Focus or Zerene Stacker. I don't remember which. Photoshop CS6 and Pixel Genius PhotoKit and Sharpeners were used.
Fifteen years ago I would have had fun with this image in a wet darkroom. With the use of Kodalith masks, pin registration and a color enlarger, I could have generated a comparably interesting image. It would have taken a few days and involve maybe fifty exposures of Kodalith film and lots of printing on paper with different colors and masks.
