Not a very nice day here, so indoors this afternoon.....

All K5, body only.
Attached via the Pentax Microscope Adaptor to my microscope.
Polarising filters both above & below the stage.
Manual focus with the microscope coarse & fine adjusters.
Focus light, an led torch.
Imaging source, Pentax AF 280T, manual, white paper reflector angled under the microscope stage.
100th. sec., ISO 100.

The urea comes from work, where it's used (Adblue) as an additive for our lorry to reduce emissions

A clone of the venerable Swift 950. That's a nice result considering the optics!

I used to do similar photos of thin rock sections when I was a Photographer at University College London, Geology Department -- I had a Zeiss Photomicroscope and used 'Ferraniacolor' Tungsten Balanced film and also I tried 'Gevaert Scientiacolor Negative ' film , both of which I processed myself.
been a member of Pentax Club since the Ron Spillman era! Got COMPUTERISED at last - DIGITISED? Taken the PLUNGE - BUT FILM STILL RULES !!!
