Goldenrod - Solidago in reflected ultraviolet photography and simulated bee vision

Today shots of a flower, Goldenrod - Solidago in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz flourite 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 bee vision image using experimental XBV filter:  

Triptych of the above images:  


This flower shows a fine UV pattern, a bit hard to see as the inflorescence consists of so many tiny individual flowers, as its petals are very UV bright (around 365nm) and its center is UV dark, and all this gets nicely visible.


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

Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography and simulated bee vision

Today shots of a flower originating from the USA Prairie, black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Simulated bee vision image using experimental XBV filter:  

Triptych of the above images:  


This flower shows a very prominent UV bullseye pattern, I would even say it is one of the most known flowers with UV pattern, as its petals are very UV bright (around 365nm) to about the middle and its center is UV dark (aging spots on this older flower can bee seen in UV+BV), and all this gets nicely visible.

I have previously written about that flower HERE.

Ashy Sunflower - Helianthus mollis in reflected ultraviolet photography and simulated bee vision V

Here even more shots of that special Prairie flower, Ashy Sunflower - Helianthus mollis in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Simulated bee vision image using experimental XBV filter:  

Triptych of the above images:  


Also here this flower shows a very specific and unique UV pattern, its petals are UV reflective around 385nm up to the middle (which I haven't seen anywhere before) and additionally reflect at 365nm at its tips and the rest and its center is UV dark forming an UV bullseye pattern, and all this gets nicely visible. It turned out to be quite difficult to map this specific pattern into the bee vision image. I will do more research about this species...
