Today shots of a decorative flower of a common herb, Borage - Borago officinalis in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was my CERCO 94mm quartz flourite lens. Light source was a high power Xenon flash. All shots were done at about f8.

Diptych of the above:
This pretty blue Borage flower has no very specific UV pattern, its petals are UV dark on the middle and bottom, but its petal tips are quite UV bright around 380nm, and all this gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
