    A quartz crystal etched in hydrofluoric acid (DANGER! don't try this at home!) and photographed with differential interference contract (DIC) microscopy.

      That's a nice photo. What film and microscope! Fracture surface or polished?It should be in the Fractal Group Pool.

      From memory, it's standard colour print film in a fairly standard Leitz optical microscope fitted with the DIC module, which generates the colours. DIC is normally used for imaging almost-transparent biological specimens so you can actually see something!

      It's a polished surface - but aligned with a specific crystal plane (111).

      Good idea - added to two of the fractal groups.
