(simulated bee vision) Bidens ferulifolia
« on: June 05, 2010, 05:59:25 AM »

Well, since a few years now I work in the field of UV (ultraviolet) photography, to be able to make visible
what some bees, butterflies, fishes, voles, kestrels etc. can see - most of them are tetrachromats, i.e.
have 4 types of cones in their eyes which enables them to see much more than we humans do.

My work has been featured by BBC1 London, which was aired a few weeks ago in "Richard Hammond's
Invisible Worlds" and which will soon also be aired in Discovery Channel.

Here now an example of a Bidens flower in VIS (human vision) and BV (butterfly vision). Note the
difference in pattern of that -to us- purely yellow flower, it is not for tetrachromats like butterflies!

I'm not going into the (complicated) technical aspects of shooting that now, which is in my BLOG,
I justed wanted to present some of my work here, in case there would be some interest in that
quite "exotic stuff" (??)

...and yes, it is possible to do this stereoscopic, just managed to make that work.
