Sanvitalia procumbens (Creeping Zinnia): human vision vs simulated bee vison; reflected UV ultraviolet photography II

Today again about Sanvitalia procumbens ("Creeping Zinnia"). So here it is in its multispectral representation with a focus on simulated bee vision; before I had shown it with a focus on UV using the Baader-U and Jupiter U filters. 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 XBV5 filter respectively.

This flower has a prominent UV reflection (around 360nm) of its petals and is one of my "standard UV targets"

As you may have noticed, I'm still working on my bee vision (BV) filters; here again it shows, how well they are able to reproduce the UV patterns together with teh visible parts a bee is able to see.

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

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