Ladyslipper - Cypripedium candidum in reflected ultraviolet photography II

Today again more shots of a decorative flower, a white Ladyslipper - Cypripedium candidum in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sun. All shots were done at about f5.6.

This white Ladyslipper flower has a very unusual UV pattern, reflecting at 360nm (yellow), 370nm (white) and 385nm (purple). All gets nicely visible here.

I have before posted about this flower in more detail HERE.

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