Tripod, Nikon D700 Nikon 100 macro (yes Nikon!) Dark ground illumination: twin flash 1/32 power, ISO 200 -0.67, 1/60 sec f20
This little chap was swimming in my garden pond and before he knew it he was photographed in a very small trough using dark ground illumination. This is a technique originally developed for light microscopy. In a nutshell the subject is placed over a dark surface and it is illuminated by back lit light that the subject has refracted into the optical axis of the lens. I made a mask of the subject and cleaned the background. The big disadvantageof this technique is that every tiny weeny particle in suspension refacts light and is clearly visible.
All C&C welcome
