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

Again about Zinnia angustifolia, that special mexican variety. So here a Z. angustifolia flower specimen which has no visible patterns actually shown in its multispectral representation (with patterns). 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 very nicely its well known deep into reaching UV tip pattern, that is completely invisible in human vision. To map that into a bee vision representation is rather tricky as it reacher quite deep into UV.

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...
