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

From a walk through the beautiful Hermannshof, Weinheim, Germany I brought home these shots of a mix of flowering Zinnia angustifolia, that special mexican variety. 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 XBV2 and new XBV6 filters respectively. So here comes Z. angustifolia in its multispectral representation.

These Zinnia specimens expose their well known deep into reaching UV (<360nm) tip pattern very nicely, on some there even is no visible pattern 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.

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