Mexican Zinnia - Zinnia haageana in reflected infrared photography IX

Today more different shots of those very decorative flowers, various types of Zinnia haageana - Mexican Zinnia but in reflected infrared photography using just a ND filter and a UV/IR Cut filter for the visible light shots. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f8.

All diptych images show left results using UV/Cut filter for the visible shots and right a ND filter for the (mostly) reflected NIR shots.

Mexican Zinnia flowers have a very specific visible pattern that also somewhat washed out gets visible in the mostly NIR shots, and all this gets nicely visible in this side-a-side presentation.

I have written previously about these flowers in UV HERE.

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

Eucharis grandiflora: UV induced fluorescence and reflected colorful UV photography II

This is again about: Eucharis × grandiflora, also called Amazon Lily this time using my "work horse" UV filter, the Baader-U filter and a Hamamatsu f3.5/50mm 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.

Also here not much prominently visible 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...

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.
