Day Lilly hybride - Hemerocallis in reflected ultraviolet photography and simulated bee and butterfly vision II

Today shots of another Day Lilly - Hemerocallis hybride in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were done at f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

Day Lilly flowers have a distinct UV reflection, its petals have a quite UV dark center and the outside part is quite UV bright around 370nm and all this gets nicely visible, also in simulated bee and butterfly vision.

I have written about that flower before HERE
 
Stay tuned, more will follow on that fascinating subject...

Day Lilly - Hemerocallis lilioasphodelus in reflected ultraviolet photography and simulated bee vision III

Today shots of an attractive summer flower, a creamy yellow Day Lilly - Hemerocallis lilioasphodelus in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my proprietary XBV filter. Lens was my ZEISS UV-Planr f2/62mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Most Hemerocallis have a very prominent "dark throat" UV pattern, and that gets nicely visible here, also in simulated bee vision.

I have previously written about that flower HERE

Hemerocallis (Day Lilly): human vision vs simulated bee vison; reflected UV ultraviolet photography

Today on my walk in the beautiful Hermanshof Park, Weinheim I discovered flowering Hemerocallis (Day Lillies), various varieties. So here comes one, a creamy whiteish yellow colored variant in its multispectral representation. I took some shots at Hermannshof, Weinheim, Germany in normal human vision VIS, in UV using the Baader-U filter, as well as in simulated bee vision using my new XBV2 and XBV6 filters respectively.

Simulated bee vison using XBV2 filter:


Simulated bee vison using XBV6 filter:


UV using Baader-U filter:


Most Hemerocallis have a very prominent "dark throat" UV pattern, and also here that gets clearly visible.

As you may have noticed, I'm still working on my bee vision (BV) filters; BV6 is one with very intensive colors and much shorter exposure time, due to new filter glass combinations.

More about these special new filters here later in a seperate entry.


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