Rose hybrid - Rosa sp. in reflected ultraviolet photography and simulated bee and butterfly vision

Today shots of a Rose hybrid - Rosa sp. in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were done at f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

This rose has just a little UV reflection around 380nm, its petals have some UV dark center and the outside part is a bit UV brighter around 380nm and all this gets nicely visible, also in simulated bee and butterfly vision.


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

Missouri Coneflowers have a distinct UV reflection "bulls eye" pattern, its petals have a quite UV dark center and the outside part is quite UV bright around 365nm and all this gets nicely visible, also in simulated bee and butterfly vision.

I have written about that flower before HERE
