Today I discovered some flowering Rudbeckias. So this is R. hirta and wanted to show this one in its multispectral respresentation. So I took some shots in normal human vision VIS, in UV using the Baader-U, Jupiter-U and the new Saturn-U (300-350nm) filter, as well as in simulated bee vision using my XBV2, XBV3 and the new, stricter XBV5 filters respectively.

IR (basically) as it was shot using only a ND filter:
And here a polyptych of a few of those images:
As you may have noticed, I'm still working on my bee vision (BV) filters; BV5 is a very strict one that cuts all longer than short wave green.
More about these special new filters here later in a seperate entry.
Stay tuned, more will follow on that fascinating subject...
