Desert Rose (Adenium obesum) in 3D and butterfly vs human vision

My Desert Rose (Adenium obesum) started to blossom, so here a few shots (crosseyed viewing)

3D Human Vision Image:


3D Butterfly Vision Image:

not much of an UV pattern to see though....

Well, I couldn't believe it, so I tested several possibilities and using some nearly monochromatic UV LED light, a UV pattern gets visible. The multspectral filtering BV overlaying three channels simply cannot make it visible (yet...). This is though the Baader U-filter + UV Rodagon 105mm.

Here now a comparison UV LED versus filtered Xenon flash both using Baader U filter (black and white images for better comparison).


Xenon flash:

the monochromatic UV LED light reveals even more details of that UV pattern!

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