Today even 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.

Diptych form for better comparison:
Here, the idea was to show not only that unique UV pattern this flower has, but to also show how that might look like for the somewhat blurry vision a bee has for flowers in further distance (flower in the background). Still the background flowers are noticeable through their unique UV pattern, albeit not as sharp as the one closeup. All that gets nicely visible here.
Stay tuned, more will follow on that fascinating subject...
