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

Another walk through the beautiful Hermanshof Park, Weinheim let me discover some flowering Rudbeckias. So here again comes R. fulgida in its multispectral representation of which I have presented a different one before. 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 XBV2 and new XBV6 filter respectively.

This Rudbeckia exposes its well know UV bullseye pattern very nicely and with that really stands out very "bee visible" from its surrounding background.

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...
