Zinnia hybride: human vision vs simulated bee vison; reflected UV ultraviolet photography

I had discovered a special Zinnia hybride flower a few days ago and since I was working on a new filter, here again it is in multispectral representation. I took some shots in normal human vision VIS, in UV using the Baader-U and Jupiter-U filter, as well as in simulated bee vision using my XBV2, XBV3 and the new, stricter XBV5 and XBV6 filters respectively.

UV using Jupiter-U filter:


IR (basically) as it was shot using only a ND filter:


Quite interesting how this new filtering technique makes the very different reflectance of the petal upper-/undersides visible:



As you may have noticed, I'm still working on my bee vision (BV) filters; BV5 is a very strict one that cuts all longer than short wave green, wheras BV6 now is one with very intensive colors and much shorter exposure time, due to new filter glass combinations.

More about these special new filters here later in a seperate entry.


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