Eucharis grandiflora: UV induced fluorescence and reflected colorful UV photography

Today about a flower I haven't posted about: Eucharis × grandiflora, also called Amazon Lily. I was using my "work horse" UV filter, the Baader-U filter and my CERCO quartz fluorite lens. Light source was an UV enhanced Xenon flash and a Nichia UV torch for the UV induced stimulated visible fluorescence (UVIVF) shot.

Not much prominent UV pattern, except that the base of the flower, where usually nectar can be found, lights up, as well as its pollen does.

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