    is this used in medicine? Is it as simple as attaching a filter to my camera and cranking up the ISO? What do you call such a filter? :)

    Filming with a UV-only light source is a popular thing during night dives. Almost every organism looks different when lit with an unusual spectrum.

    What puzzles me is the ever changing tides of hysterical advices in medicine. Not many decades ago, little children were systematically exposed to ultraviolet light by doctors to prevent rickets. Today children are kept from exposure to sunlight as if they were vampires. Gee, everything is toxic in excessive doses. Even substances contained in sun blockers are.

    And one thing is for sure: Every year additional average life expectancy will be accompanied by an increased ratio of deaths resulting from cancer.

    They Live!

    Too much sun/surfing in my youth, paying for it now. Still need vitamin D, achieved in about 10 minutes a week, middle of the day where I live, all the year.

    I can certainly bring out skin damage with aggressive and abrasive colour correction, although not the same as this sample. Thanks for posting.

    @WhiteRabbit: have you done your calculations on that? I would be interested in the math, as I get much more time needed in the sun. :)

    @fatpig, actually, correction, 20 mins per week advised by skin specialist doctor, by referral from general practitioner. 20 mins made up by 2x 10 mins on two different parts of my body that have not been damaged by the sun, mostly from surfing for 20 years. 10am to 2pm all year, I was advised that you'll get the Vit D needed where I live. YMMV, not advice. Have a good one!

    Sorry to hear about those skin damages. Does not sound nice..

    I see you are in good care. I would advise anyone to get their levels tested, though. Also, the sun doesnt come up high enough in the winter months for vitamin d production. There is even a calculator on the website of the military for that. its a whole science :-P
