Dwarf Tulip - Tulipa pulchella violacea in reflected ultraviolet photography, simulated bee and butterfly vision

Today also about an early spring flower, a Dwarf Tulip (Tulipa pulchella violacea) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

Simulated bee vision (UV - VIS) using XBV6 filter:
 

Quadtriptych of the above:
 

This dwarf tulip has a quite visible UV pattern, its center is UV bright, surrounded by long wave UV reflecting tips and all this gets quite nicely visible.

Stay tuned, more will follow on that fascinating subject...

Pasque Flower - Pulsatilla vulgaris in reflected ultraviolet photography, simulated bee and butterfly vision

Today about an early spring flower, a Pasque Flower (Pulsatilla vulgaris) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6. I have already written about that flower before.
