360 degree microphotography

Summary: we took a microscope objective to my camera, built a focus stacking rig, and then combined it all with a miniature lazy susan / turntable to create a 360 degree rotation animation of a microscopic thing (in this case a common green long-legged fly, which has some pretty spectacular colors).

Quick details:

  • Each frame is a stack of 70 images
  • 160 frames (about 2.25 degrees of rotation per frame)
  • Final is the product of 11,200 frames (though we took well over 20,000 while testing/developing)
Gear setup:
  • Fuji X-T1
  • nameless eBay macro photography bellows
  • nameless eBay RMS adapter
  • AmScope PA4X microscope objective
  • Arduino Nano
  • Misc stepper motors and motor drivers
  • Custom motion control rig for focus stack and rotation
