[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.

Standardized reflected false UV "colors" according to the previously described "UV color palette" related to wavelength.

Standardized false UV color normal + high intensity palette:



VIS:


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


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


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...
