I had discovered some flowering Rudbeckias the other day. So this is another R. hirta as I have shown before and I wanted to also show this one in its multispectral representation. 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 and butterfly vision using my XBV2, XBV3 and the new, stricter XBV5 filters respectively.

UV using Saturn-U (300-350nm) filter:
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...
