Rudbeckia triloba: human vision vs simulated bee vison; reflected UV ultraviolet photography

Today about a Rudbeckia triloba in its multispectral representation, shot in Herrmanshof Park, Weinheim, Germany. I took the shots on a very windy and cloudy day using sunlight in normal human vision VIS, in UV using the Baader-U filter, as well as in simulated bee vision using my XBV2, XBV6 and XNUV filters respectively.

And here a polyptych of them all:

The new filtering technique makes the very prominent UV reflectance of the petals clearly visible.

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