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

Today on my walk in the beautiful Hermanshof Park, Weinheim I discovered more flowering Zinnia angustifolia, that special mexican variety. So here comes another Z. angustifolia, an orange 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.

Here a quadriptych of these:

This Zinnia specimen exposes its well know deep into reaching UV tip pattern very nicely and in teh visible, do not show anything of it at all.

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...
