Treasury flower - Gazania rigens in deep reflected ultraviolet photography, simulated butterfly and bee vision V

Today more about my last surviving Gazania flower Treasury flower - Gazania rigens in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens used was the 94mm CERCO quartz fluorite lens. Light source was a modified for UV high power Xenon flash.

UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):

Simulated butterfly vision (UV - VIS) using XBV4 filter:

Simulated bee vision (UV - VIS) using XBV6 filter:

Simulated bee vision (UV - VIS) using XBV5 filter:

Quadriptych of some of the above:

Interesting to notice also here, how the visible details change when the used wavelength gets shorter and the then appearance of unique colors when the butterfly and bee vision filters are applied. The outer petals reflect strongly UV around 370nm, there are also highly reflecting marks inside around a dark UV center and all that gets nicely visible, which I have also previously shown.

There is a Part IV about this same flower using filter stacks HERE.
There is a Part VI about this flower HERE.

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