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

Today shots of a spring flower I have written about before, Creeping cinquefoil - Potentilla reptans) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filter for simulating bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

Visible light image:
 

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

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

Triptych of the above:
 


This Potentilla flower has quite a prominent UV pattern, its center is UV dark and the tips of its petals are UV bright (reflecting around 365nm) and all this gets quite nicely visible.


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

Spring Flowers 2014: Creeping Cinquefoil - Potentilla reptans - 80mm Quartz Fluorite lens for reflected ultraviolet photography II

Here today again shots of the well known Creeping Cinquefoil - Potentilla reptans early spring flower. Shots were done aside from visible photography in reflected ultraviolet using Baader-U and the deeper reaching Jupiter-U filter, as well as in simulated bee vision using my XBV6 filter. Lens used was my X80QF f3.2 / 80mm Quartz Fluorite lens. Light source was sun. All shots were done at approx. f8.

UV image using Jupiter-U filter (approx. 280-385nm, effective peak approx. 365nm):  

Simulated bee vision image using experimental XBV filter:  

Quadriptych of the above images:  


This Potentilla flower has a well known bulls-eye UV pattern, its center is UV dark, whereas its petals strongly reflect around 365nm. The X80QF quartz fluorite lens is reproducing this quite well and all that gets 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 II

Today about another early spring flower which I have shown here before in close-up, 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.
