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.

UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):
 

Simulated butterfly vision (UV - VIS) using XBV3 filter:
 

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 ware UV reflecting tips and this gets quite nicely visible.

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

Creeping Cinquefoil - Potentilla reptans flower in reflected UV ultraviolet photography and simulated bee vision

Today about another early spring flower, Creeping Cinquefoil (Potentilla reptans) 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.

This Potentilla flower has quite a prominent UV pattern, its center is UV dark and this gets quite nicely visible.

An overview, "meadow" shot may be seen here.

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.
