Moth Orchid - Phalaenopsis multispectral

[Dr Klaus Schmitt]

This series with an yellow-orange moth orchid was shot using my trusted UV-Nikkor 105mm using specialized filters on my full spectrum converted Panasonic Lumix GH5 with a modified Xenon flash as a light source.

Another interesting set Klaus.
I personally think we get the most attractive version here, closely followed by butterflies.
Others will no doubt order them differently.

My preference is the UV reflection!

But, Klaus, how did it come to be this lilac color in visible light? Was their a vote or that’s what the filter converts it too, or that’s the wavelength of the reflected light?

Thanks guys!

Asher, that "UV color" is artificial, but appears when there is some long wave UV reflection around 380-385nm. It is a whitebalanced image using SPECTRALON (R) but those "colors" strongly depend on teh Bayer pattern a chip manufacturer has used, more precisely their transmission in the UV and the reaction of the siicon photo diodes underneath. A rather complex thing it is. I have tested that with my LUMIXes over the years using narrowband UV light by using a monochromator and these are the resulting artificial "UV colors" then. I have that explained in more detail: HERE

This on the right side for instance is a flower (Mexican Zinnia) which reflects at much shorter UV wavelengths....
