Flourescent Lilly using UV LED torch
Here a result of some fluorescence study using that wonderful Lilly flower I had used before.

[UV] Lilly "retro style" using UV-Sonnar 105mm and Polaroid film
Today a leap back in time. Let's dig out the old photo gear and see what could be done with that. Let's go retro!!
So I grabbed my Hasselblad 500C/M, my UV-Sonnar 4.3/105mm, that special Schott UG11 UV transmission filter that came with that rare lens, a Polaroid back and some Polaroid 100 bw film (good till 1987, just "a little" outdated I have to admit). Exposure was ISO80, 1/125, f8 using a 400Ws Xenon flash.

Considering the effort and hit rate, I know now how spoiled I am shooting digital!! Same done digital here.

White Lilly - a surprising lens find for UV and VIS w/o focus shift II
Well, a while ago I was doing these "Psychedelic Lilly" test shots here . Prior to that I had taken UV transmission tests of that very interesting lens family, which turned out to be very promising, reaching down to about 320nm (-3EV). Here now more about that.
These macro shots were done at f8, ISO400, 1/160s using Xenon flash, exposure adjusted using flash power control and ND filters. UV shots were done using the Baader-U filter.

Here now a VIS-UV differential:
Quite a sharp lens with quite good UV transmission and hardly any focus shift, as the two overlaid images nearly perfectly match!
Here the VIS shot:
and the UV shot:
Finally now the VIS-IR differential:
Stay tuned, more will follow on that fascinating subject...
