Gazania splendens: human vision vs simulated bee vison

This now is about a Gazania splendens flower that just blossomed. Took some shots, in normal human vision, in UV using the Baader-U filter as well as in simulated bee vision using my XBV2 and XBV3 filters respectively.

So and here you have the full comparison as a quadriptych VIS-UV-BV2-BV3:




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

Gazania rigens: human vision vs simulated bee vison

This now is about a Gazania rigens flower that today started to blossom again. Took some shots today, in normal human vision, in UV using the Baader-U filter as well as in simulated bee vision using my XBV2 and XBV3 filters respectively.

Sanvitalia procumbens: Simulated bee vison filter - improved version 3

So this is about tuning my proprietary Bee Vision Filter (that simulates the UV-Blue-Green vision of a bee in just one shot). Here again it is used on a Sanvitalia procumbens flower. As the greens were a bit underrepresented (take the green bud left for example) in my current XBV2 filter, I optimize my filter stack to get "better" greens in my new XBV3 filter.

For comparison, the normal vison:


So in my opinion, the new version XBV3 represents the leaf color better, yet still brings out the UV marks as white petal tips nicely.


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