Harald Posted February 21, 2020 Share Posted February 21, 2020 Hi,Here is Sodalite from Greenland.I will work on my lighting. Planing to make a black box to photograph my UV minerals The specimen is about 12mm wide, lighted with my trusty Convoy S2 and EOS 5D II with MP-E65 Edit: Sodalite is the type locality of Ilímaussaq complex, Narsaq, Kujalleq, Greenland, Denmark Link to comment
Stefano Posted February 21, 2020 Share Posted February 21, 2020 This is a famous UV fluorescent mineral. The fluorescence should also be pretty bright, right? It would be interesting to see if UV in sunlight makes a difference in the appearence of this mineral (like what Andrea thought about flowers here: https://www.ultravioletphotography.com/content/index.php/topic/3693-heres-one-for-you-to-try/page__view__findpost__p__32640__hl__dome__fromsearch__1).

OlDoinyo Posted February 21, 2020 Share Posted February 21, 2020 In northern Michigan, this mineral has been known as 'yooperlite." It is sometimes found on the shore of Lake Superior. Link to comment
dabateman Posted February 21, 2020 Share Posted February 21, 2020 Harold,Do you also have a 254nm short wave UV source light to visualize minerals?These are typically small 4W bulbs with a protective filter.If you do it would be great to see a comparison between the short and long wavelengths UV fluorescence. Remember to be extremely careful with the UV source lights. Link to comment
Harald Posted February 22, 2020 Author Share Posted February 22, 2020 Hi all,Thanks for your kind comments :D Da Bateman:"Do you also have a 254nm short wave UV source light to visualize minerals?"No, I don´t, but looking for "Remember to be extremely careful with the UV source lights."Allways Link to comment
