Flowers in Visible and Ultraviolet A Light, Blurry, 1st Try...

1st try pairs of photos in UVA and visible light, UVA blurry. Focus position is a guess, UV focuses in a different place further away, with 50mm f/3.5 uncoated fused quartz lens and a #403 320nm to 380nm passing filter (very black). Exposure also a guess, +12 f/stops for filter. More experimentation needed.

    I don't think I've seen photos exposed for UV before, very cool.

    @alburnkat I think this is a 1st for Lomography, I can find no others here. The tools to do this are uncommon, and I read about it here: www.naturfotograf.com/index2.html and I got lucky on eBay auction. The fused quartz uncoated lens can get bid way up if a couple bidders recognize it and need it... www.lomography.com/homes/herbert-4/photos/18892420 It's no name, but I think it's a UKA.
