Gaillardia "Summerwind"

Well, I found a previously unknown (to me), pure yellow species of Gaillardia. Since that type of flower showed so many surprising aspects, I wanted to see what this new one hides from the human eye....

This now is the visual appearance as we humans are used to see:



The tetrachromatic image ("butterfly" shot) (UV+B+G+R) using XBV2 filter:



The trichromatic image ("bee vision" shot) (UV+B+G) using XBV2 filter:



This is the UV induced fluorescence shot using XCUT2 filter:



and this the reflected UV shot using XUVIR filter:



Well, also that flower shows some surprising properties ...

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

Gaillardia - trichromatic bee vision

This is about an interesting find, when I was wondering around in parks taking shots using my "bee vision" filter XBV2. I know that prominent "Gaillardia" flower since I was a kid, but I never thought that it would exhibit some prominent UV pattern - but it does! Have alook at my results, before we discuss that:

I found it especially fascinating, that the red part of that prominent Gaillardia pattern has a very strong UV reflectance, accompanied by a prominent pattern the petal tips exhibits (UV+Green) so as to generate that "heliport landing spot" pattern. Is it just a coincidence that the pollen exhibits the very same color (and do I see some fluorescence there - to make the pollen look even brighter??)

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