A walk today in the beautiful Hermanshof Park, Weinheim let me discover some flowering Opuntia humifusa, the reclining Opuntia. So here it comes in its multispectral representation. I took some shots at Hermannshof, Weinheim, Germany in normal human vision VIS, in UV using the Baader-U filter, as well as in simulated bee vision using my new XBV6 filter respectively.

UV using Baader-U filter:
Simulated bee vison using XBV6 filter:
This specimen has very bright pollen even at daylight, which the XBV6 filter nicely shows. Reminds my of UV induced fluorescence photography. In UV the petals have a metallic like shine that reflects UV strongly, maybe to attract pollinators?
As you may have noticed, I'm still working on my bee vision (BV) filters; BV6 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...
