Today more shots of a cultivar flower, originating from the USA Prairie, a Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee and butterfly vision using my XBV filters. All shots were done at f11. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was a modified Xenon flash. This was shot using my previously used modified high resolution camera (40/80Mpix), an Olympus M5 Mk2

This flower shows a very prominent UV bullseye pattern, as its petal tips are very UV bright (around 365nm) to about the middle and its center is very UV dark, and all this gets nicely visible also in simulated bee and butterfly vision. I have matched the previously done shooting for comparison reasons.
I have previously written about that flower HERE
Stay tuned, more will follow on that fascinating subject...
