Here a test shot of a Creeping Zinnia "Sanvitalia procumbens" flower, using a 2 shot stereo method with my UV-Rodagon 5.6/105mm lens. This is for cross eye viewing.

First some visible light shot (actually that was filtered out using the Baader UV/IR Cut filter and the rest setup was the same, to make sure I'm not seeing UV induced visible fluorescence):Simulated Butterfly Vision (UV=blue) using my XBV2 filter:
and another one:
Sanvitalia is difficult to bring out the UV pattern, as that one happens much deeper in the UV region as with other flowers having that.
Stay tuned, more will follow on that fascinating subject...
