Today shots of some decorative flowers, all Zinnia haageana - Mexican Zinnia in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was a UV transmitting 100mm lens. Light source was sun. All shots were done at about f11.

All images are reflected UV images, using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm); two different white baklancing methods were used.
Hexaptych of some of the above:
These Mexican Zinnia flowers have a very specific UV pattern, its petals are very UV dark on the middle and bottom, but its petal tips are very UV bright, reaching much deeper into UV as any other flower I know, reflecting UV in the greenish appearing region below 345nm, and in the yellow areas around 360nm and all this gets nicely visible.
I have written previously about these flowers HERE, also showing them in simulated butterfly + bee vision.
Stay tuned, more will follow on that fascinating subject...
