Experiments with Full Spectrum Camera

[pleecan (Peter Lee)]

Modifications of Sigma SD10 Foveon camera:
I removed the hot mirror which removes UV and IR light from the camera... creating a full spectrum camera sensitive IR-Vis_UV bandwidth. I then placed a cross polarizer filter in front of camera to produce these images....
Lens is a 50mm F2.8 Sigma EX Macro lens.

Interesting effects - well worth playing around with. You'll probably get more interesting results from polyphase specimens, though - things like ammonites with multiple cement stages, or arthropods with remaining cuticle and partial replacement. As far as I know, using unusual wavelengths works really well for a few types of material, but doesn't do much at all for the rest.

Fun to play with ..... I read that some digital cameras are super sensitive in the IR band / UV ...
