[VIS, BV, UV] Sanvitalia procumbens: visible, ultraviolet, bee vision

Sanvitalia procumbens shots using the CERCO 94mm lens, mod. Xenon flash, ISO200/400, 1/125s, f5.6. The needed adjustments were done by adjusting the flash energy and using a ND filter for the VIS shot.

Baader UV/IR CUT filter (VIS):



XBV3-filter (BV bee vision):



Baader U - filter (UV):


Interesting to note, that the lower flower has much less of an UV pattern maybe denoting a different ripening status?


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

I found this ensemble rather interesting, as I could get an "unripe" flower bud also into the picture (top right) - without signs of an UV pattern.

Now one day later I took another series of shots (a bit differently processed though), here they are:
