Oncostele Wildcat 'Golden Red Star' in visible and reflected ultraviolet (UV) light

Today shots of an Orchid hybride, Oncostele Wildcat 'Golden Red Star' in reflected ultraviolet photography with a UV-Nikkor f4.5/105mm lens. UV filter used was the Baader-U filter, my "work horse" filter for reflected UV. All shots were done at f8 for the UV-Nikkor. Light source used was a modified for high UV output Xenon flash.

Visual vs reflected UV (Baader-U):

This orchid has a very specific UV pattern, its petals are very UV dark, but its lower petal lip has on the lower center a very UV bright spot as well as on its center "nose" formation an UV reflecting spot and all this gets nicely visible.

I have written more about this orchid HERE

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