Summer UV flower potpourri in reflected ultraviolet photography and simulated bee vision

Today studio images of a summer flower potpourri, all exhibiting UV patterns, shot in reflected ultraviolet photography and simulated bee and butterfly vision. Flowers shown are: Rudbeckia fulgida, Gazania rigens, Sanvitalia procumbens and Bidens ferulifolia. All shots were done at f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated bee and butterfly vision. This used butterfly vision simulating filter is a new development of mine. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was a modified Xenon flash, background was a dark gray. [These shots were done with a new camera system and are available on request in very high resolution (40 and 60 Mp)].

These flower outer petals reflect UV strongly, contrasting against its UV dark center, all invisible to us humans, but all this gets nicely visible, also in simulated bee and butterfly vision.

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