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...

Bidens ferulifolia, various filters + light sources

Well, another nice target for UV photographic experiments is Bidens ferulifolia, the variety "Peters's Surprise".

Equipment used was: Nikon D70 (unmodified), ISO400, f5.6-8, 1/160sec, old 100mm enlarger lens.

VIS using XCUT2 filter (400-650nm):


UV using Baader U-filter (310-390nm) - synthetic DOF:


XUVIR multispectral filter (300-1000nm), UV Flash:


UV induced fluorescence using XCUT2 filter (400-650nm), UV flash:

So, as you may see, a variety of results also that flower shows us.

P.S.: if you wonder what "synthetic DOF" means, I used "stacking" to increase the DOF artificially.

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