[UV] Rudbeckia flower - reflected UV ultraviolet HDTV video

Today about UV videos, here using a Rudbeckia fulgida and R. hirta as examples. These flowers exhibit a very prominent UV bullseye pattern, which I would like to present here as a HDTV video; before I had shown UV video snippets in May 2009 as a preparation for the filming of BBC's "Richard Hammonds Invisible Worlds".

These videos here also use my Standardized false UV color normal + high intensity palette:

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

[UV, FL, VIS, NIR] A very special Zinnia from Mexico

Today about a very special Zinna flower from Mexico, the boss of our most beautiful park Hermannshof, Weinheim, Prof. Cassian Schmidt gave me for my research and photographic work.

This special flower exhibits very prominent patterns under various filtering and lighting conditions which I would like to present here.

Standardized false UV color normal + high intensity palette:



VIS:


UV using Baader-U2 (320-390nm):


UV using 333nm narrowband filter (325-340nm):

So I hope you liked that too!

[UV] Zinnia shot at 333nm UV in the field

Today about shooting Zinnias at 333nm in the field as I wanted to see, if it was doable.

and another one:

VIS:


UV using Baader-U2 (320-390nm):


UV using 333nm narrowband filter (325-340nm):


It seems to be doable on bright sunny days as it was today, but one has to certainly pray for less wind, since the exposure needed for the 333nm shot was substantially longer, 1-2sec @ISO1250.


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