baffe Posted July 3, 2014 Share Posted July 3, 2014 Hi!My name ist Stefan, I'm german and this is my first post here. I mainly try to make photos of uv induced visible flourescence. Actually I'm working on a flashlight that produces bigger amounts of uv than filtered common xenon flashes do.I must admit that I haven't succeed yet. But I'm still working on that. I also equipped some flashes with filters and did some shots (like the Stones below). Looking for suitable uv light sources I was doing some tests with led's. With some funny and, -at least for me-, surprising results. I read a lot of interesting facts here and now I'd like to introduce myself.Cheers!Stefan Link to comment

JCDowdy Posted July 3, 2014 Share Posted July 3, 2014 Welcome Stefan!Over here in the US a flashlight is what you would call a torch, hence my slightly confused condition. :( Link to comment
baffe Posted July 3, 2014 Author Share Posted July 3, 2014 Hi! The first stone is Calcite, the second is Franklinite with Willemite and Calcite and third is scapolite (wermerite). First shot of each stone is made with standard flash unit, the second by means of uv-flash units. Thank you John, it was not a torch. The second picture shows flourescence as cam is almost blind to uv (always Pentax k-x, Kiron 105mm/f2,8 macro lens, no filter on cam) baffe Link to comment
