Daucus carota in reflected ultraviolet photography II

Today more detailed shots of that flower of the Apiaceae family, Wild Carrot - Daucus carota 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 sunlight. All shots were done at about f5.6. I have written about that flower HERE before.

Diptych of the above images:  

This pretty flower (an inflorescence actually, consisting of many small flowers) has a specific UV pattern, its little individual flower petals are UV bright around 385nm and its pollen seems to reflect around 365nm, and all this gets nicely visible.

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