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

A walk today in the beautiful Hermanshof Park, Weinheim let me discover some flowering Rudbeckias. So here comes R. missouriensis in its multispectral representation. I took some shots 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.

This Rudbeckia shows its well known "UV bullseye pattern" very nicely.

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.

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