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...
