Today more reflected ultraviolet photography shots using that old achromatic quartz fluorite lens, that I have rescued from an older spectrometer system also using my "work horse" UV filter, the Baader-U filter (approx. 320-395nm, peak approx. 350nm) with a Zinnia haageana flower. Light source was a Xenon flash system. All shots were done with variated aperture settings (+1 stop difference per image) to show that influence.

Quadriptych form for better comparison:
So, I guess the idea gets clear to get some softness into the image, yet preserve the structure of the flower and especially its unique UV pattern. And that gets nicely visible here.
More about that used quartz fluorite lens is HERE.
Stay tuned, more will follow on that fascinating subject...
