Shot that most likely genetically modified Gazania rigens flower using an off the shelf UV Nikkor 105mm at f8/f11 on a modified Panasonic GH4 with a modified for high UV output Xenon flash using modified and rather special filters Wink

Quadriptych of human vision, UV, simulated butterfly and bee vision (left to right, top to bottom):

Klaus, I love your alternate spectrum work. Perhaps after I retire I might dabble. Why do you think it's a GMO?

Dude!
UV I think I understand, but "bee vision"?

!!!!

How do you do that?

I have a Nex-3 to sacrifice to the cause of science.
But the conversion seems a bit involved!

Thannks! I assume it is a GMO breed, as I have never seen such a filled version before, but I may be wrong, it could also have been breeded by selection, but this process usually takes many generations ...

Simulated bee and butterfly vision is mapping the three for a bee (UV, B, G) or four for a butterfly (UV, B, G, R) "color" channels into our human (B, G, R) color space to make it visible (like what NASA does with their aerial and astro images). The channels (UV, Blue, Green, Red) itself need to be recorded with filters which match the eye sensitivities of bee / butterfly.
