Ladyslipper - Cypripedium candidum in reflected ultraviolet photography

Today again shots of a decorative flower, a white Ladyslipper - Cypripedium candidum in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. 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.

I have before posted about this flower HERE and HERE.

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