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.

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):

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...

Treasury flower - Gazania rigens in deep reflected ultraviolet photography, simulated butterfly and bee vision XII

Today shots, developed from RAW files, of a different orange colored specimen of that long lasting I have written about before Treasury flower - Gazania rigens 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.

Quadriptych of the above (with bee/butterfly vision):
 

This orange Gazania's outer petals reflect strongly UV around 385nm, all invisible to us humans, and there are also highly UV reflecting marks inside around a dark UV center and all that gets even nicelier visible developed from RAW.

The images developed from jpg are HERE.

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

Hawksbeard - Crepis in reflected ultraviolet photography, simulated butterfly and bee vision VIII

Today shots of another species of Hawksbeard - Crepis sp. 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, today now also using the reworked XBV4 filter. Lens was a CERCO 94mm quartz fluorite lens. Light source was a Xenon flash. All shots were done at about f8. Here now developed from RAW files.
