Today as I have shown before again R. hirta in its multispectral representation. I took some shots in normal human vision VIS, in UV using the Baader-U, the all proprietary 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 XBV6 filter respectively.

UV using Jupiter-U filter:
UV using Saturn-U (300-350nm) filter:
IR (basically) as it was shot using only a ND filter:
Rudbeckia and also this R. hrsta have a very prominent, otherwise invisible "bullseye pattern" which gets nicely visible in UV (around 360nm) and BV. Since leafs (petals were leafs one) reflect from 700-750nm onwards, that pattern is also invisible in IR.
As you may have noticed, I'm still working on my bee vision (BV) filters; BV6 now 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...

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.

Simulated bee vison using XBV2 filter:
Simulated bee vison using XBV5 filter:
UV using Baader-U filter:
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...
