Today more outdoor shots of that long blooming flower, a white-yellowish flower, a Treasury flower - Gazania rigens shot in reflected ultraviolet photography, 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 Gazania's outer petals strongly reflect UV around 365nm, whereas the inner petal parts are quite darker, hence forming UV nectar guides for UV seeing insects. There are also some highly UV reflecting marks inside around a dark UV center, all invisible to us humans, but clearly visible to bees and butterflies, and all this gets nicely visible here, also in simulated bee and butterfly vision.
I have written about this Gazania previously HERE
Stay tuned, more will follow on that fascinating subject...

Cliff maids - Lewisia cotyledon in reflected ultraviolet photography, simulated bee and butterfly vision II
Today more shots of a long blooming, perennial spring flower Cliff maids - Lewisia cotyledon 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.

Lewisia has a visible UV pattern, its petal tips are UV bright around 385nm, its center is UV dark, so this gets quite nicely visible, also in simulated butterfly and bee vision.
I have written more about that flower HERE
Stay tuned, more will follow on that fascinating subject...

Apache beggarticks - Bidens ferulifolia in reflected ultraviolet photography, simulated bee and butterfly vision XII
Today more shots of that long blooming spring flower "Rockstar" hybride Apache beggarticks - Bidens ferulifolia 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.
