Small internal shell of a cephalopod (Spirula spirula) was photographed with my new DIY Ring (rim) light adapter:
This case it was used as a rim light. It was powered with a wireless minolta 5600HSD flash.
Camera was a sony a100 with a sigma 50mm macro lens.
Straight out of camera jpeg was just re-sized.
Check the texture!!
More details about the rig is coming soon on my blog:
