Today shots of a flower, Garden Nasturtium - Tropaeolum majus 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 Xenon light. All shots were done at about f5.6.

Triptych of the above images:
This flower shows a UV pattern, its petals have some UV reflection around 385nm or the outside, inwards getting quite darker, its pollen is unsual UV light (most are quite dark), and its stamen is quite UV bright reflecting around 370nm, and all this gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
