Creeping Zinnia - Sanvitalia procumbens in reflected deep ultraviolet photography, simulated bee and butterfly vision III

Today shots of a spring flower, developed from RAW files, Creeping Zinnia - Sanvitalia procumbens in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, my Jupiter-U and Saturn-U deeper UV filters, as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was a Xenon flash. All shots were done at about f8.

Visible light image:
 

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

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

UV image using Saturn-U filter (approx. 300-350nm, effective peak approx. 325nm):
 

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

Simulated bee vision (UV - VIS) using XBV4 filter:
 

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

Triptych of the above (with deep UV):
 


Sanvitalia has a strong UV pattern, its petal tips are UV bright around 365nm and its center is quite UV dark, and all this gets nicely visible.

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

Creeping Zinnia - Sanvitalia procumbens with bumble bee in reflected ultraviolet photography, simulated bee and butterfly vision II

Today side-a-side staged shots of a bumble bee sitting on a spring flower, Creeping Zinnia - Sanvitalia procumbens 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 a Xenon flash. All shots were done at about f8.

Sanvitalia has a strong visible UV pattern, its petal tips are UV bright around 365nm and its center is quite UV dark, whereas the bumble bee is rather UV dark except its rear, which is UV bright around 375nm (as a signal to its colleagues that this flower is occupied?) and all this gets nicely visible also in this composite form.

More about that HERE

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

Creeping Zinnia - Sanvitalia procumbens with bumble bee in deep reflected ultraviolet photography

Today staged shots of a bumble bee sitting on a spring flower, Creeping Zinnia - Sanvitalia procumbens in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my deeper into UV reaching Jupiter-U and Saturn-U filters. Lens was a CERCO 94mm quartz fluorite lens. Light source was a Xenon flash. All shots were done at about f8.

I have shown that also in simulated butterfly and bee vision HERE
