Zinnia angustifolia: human vision vs simulated bee vison; reflected UV ultraviolet photography

A walk today in the beautiful Hermanshof Park, Weinheim let me discover some flowering Zinnia angustifolia, that special mexican variety. So here comes Z. angustifolia 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 XBV2 and new XBV6 filters respectively.

This Zinnia specimen exposes its well known deep into reaching UV tip 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.

More about these special new filters here later in a seperate entry.


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