bobfriedman Posted January 7, 2018 Share Posted January 7, 2018 Thought i would try out the D800M (CFA and microlenses removed, low pass filter replace with a BG-38 filter)... Leitz Focotar 50mm f/4.5, Baader U-filter... the B-100A Blak-Ray lights (2) that i have.. with the only thing i could try.. my fingers.. lights were resurrected from back in the day buried in my cellar.. used to do resonance fluorescence with them.. until i can get a better illuminator and subject?? the B-100's lamps consist of 100W mercury vapor bulbs (Sylvania H44GS 100) with a lens that bleeds red.. they get quite hot so the lens (5in diameter)is quite thick... attached image plus a crop... Nikon D800M ,Leitz Focotar 50mm f/4.5x,Ultraviolet1/8s f/16 at 50.0mm iso400 Link to comment
nfoto Posted January 7, 2018 Share Posted January 7, 2018 Apparently pBase won't allow direct linking of images. So we miss the finger impression. Link to comment

nfoto Posted January 7, 2018 Share Posted January 7, 2018 One's fingers in UV will indicate an age of > 100 years .... Tried that years ago myself. Not again. Link to comment
bobfriedman Posted January 7, 2018 Author Share Posted January 7, 2018 One's fingers in UV will indicate an age of > 100 years .... Tried that years ago myself. Not again. well with my lack of available targets, need the spring/summer for some better UV targets.. currently frigid in the northeast weather, -5degF (-20.5degC) at 8am without windchill factor.. however, i found those shots interesting in their detail..

nfoto Posted January 7, 2018 Share Posted January 7, 2018 UV always discloses additional detail. Whether or not one wants it. Link to comment
