Hemerocallis (Day Lilly): human vision vs simulated bee vison; reflected UV ultraviolet photography

Today on my walk in the beautiful Hermanshof Park, Weinheim I discovered flowering Hemerocallis (Day Lillies), various varieties. So here comes one, a creamy whiteish yellow colored variant 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 XBV2 and XBV6 filters respectively.

Most Hemerocallis have a very prominent "dark throat" UV pattern, and also here that gets clearly visible.

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...
