Today shots of another long lasting flower 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.

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 XBV6 filter:
Quadriptych of the above (with bee/butterfly vision):
Quadriptych of the above (with deep UV):
Also this Gazania's outer petals reflect strongly UV around 365nm, all invisible to us humans, and there are also highly UV reflecting marks inside around a dark UV center and all that gets nicely visible.
The images developed from RAW files are HERE.
Stay tuned, more will follow on that fascinating subject...
