[UV] Old Achromatic Quartz Fluorite Lens for Ultraviolet Photography (VI)

Today a bit different reflected ultraviolet photography shots, as I tried to work with more open aperture, using that old achromatic quartz fluorite lens, that I have rescued from an older spectrometer system also using my "work horse" UV filter, the Baader-U filter (approx. 320-395nm, peak approx. 350nm) with some Zinnia haageana flowers. Light source was afternoon sunlight.

Diptych form VIS , UV for comparison.





Here, the idea was to show not only that unique UV pattern this flower has, contrary to what we see (or don't see) in visible light, but this time with a bit "artsy" touch using wider open aperture and playing with DOF. All that gets nicely visible I think.

More about that used quartz fluorite lens is  HERE.

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