Andrea B. Posted August 14, 2018 Share Posted August 14, 2018 The female Eastern Tiger Swallowtail (Papilio glaucus) has two variations (morphs)yellow with black tiger stripes and a blue wash on the upper hind wingsdark grey or black with darker tiger stripes and also a blue wash on upper hind wingsRef: http://www.naba.org/...s#phototable-11 We'll have to use that North American Butterfly Association link for a visible reference on those two morphs because I was only photographing in UV when I caught this yellow female E. Tiger on the buddleia bush this afternoon. In UV it looks like the yellow E. Tiger has switched to her dark morph. Cool thing to discover. This was the only good(?) photo. It was made when I attempted a little movie. I was at ISO-1600 and stayed at f/5.6, but that did not quite permit fast enough speeds. And I couldn't manually focus fast enough - drat !! It was still great fun to try. Most butterfly wings are iridescent. Compare that first photo to these which seem to be slightly more UV-reflective. The underside of the wings seems to be a bit more UV-reflective. Link to comment

Andy Perrin Posted August 14, 2018 Share Posted August 14, 2018 I love the movie! Too bad we can't get it to play in-line. Link to comment
Andrea B. Posted August 15, 2018 Author Share Posted August 15, 2018 Yeah, I know. I just read that the IP Board software devs are planning to add inline video in some future release. So I will try to be on the lookout for that. Hotlinked Vimeos play here should anyone want to use that site. I think I might have a login there from long ago, so I should check. Link to comment
nfoto Posted August 15, 2018 Share Posted August 15, 2018 VLC played the video without problems. Link to comment
GaryR Posted August 25, 2018 Share Posted August 25, 2018 I meant to respond earlier, but I didn't think video would be possible with Badder U. Enjoyed seeing this video !! Link to comment
Andrea B. Posted August 28, 2018 Author Share Posted August 28, 2018 Thanks!It does require good, strong sunlight. :D The Lumix Gees are so good for UV video. That little GH1 conversion of mine is really showing its age in many ways, but I just can't quite give it up yet. I should try this with the Nikon D610 just to see what I could get. Will do!!!

eye4invisible Posted August 28, 2018 Share Posted August 28, 2018 Such sharp focus in this video. I only wish my D3200 could render UV tones like that. Link to comment
Andy Perrin Posted August 28, 2018 Share Posted August 28, 2018 I only wish my D3200 could render UV tones like that.If it's a converted camera, it should. You need to have a UV capable lens from the sticky, though (or other, if you can find one, but the sticky lenses are sure bets). The images I've seen from you look like the lens is probably the limitation. There is also the need to properly white balance. Link to comment
Andrea B. Posted August 28, 2018 Author Share Posted August 28, 2018 Andy, do you mean that you wish the D3200 would render those colors or the lights and darks? Link to comment
eye4invisible Posted August 28, 2018 Share Posted August 28, 2018 If it's a converted camera, it should.Yes, it's full spectrum converted. You need to have a UV capable lens from the sticky, though (or other, if you can find one, but the sticky lenses are sure bets). The images I've seen from you look like the lens is probably the limitation.Not really. I get the same magenta colour cast whether I use my kit lens or my EL-Nikkor 80mm. There is also the need to properly white balance.Yes, especially for video, but again it's very difficult to set a CWB on my D3200, regardless of which lens is attached. I normally set my camera to monochrome just to get rid of the magenta cast in UV video. Only yellow seems to make it through, and even then I need to reduce the magenta and boost the yellow by tweaking the HSL in Lightroom. Link to comment
Andy Perrin Posted August 28, 2018 Share Posted August 28, 2018 Ok, the problem is 100% a white balance issue. You don't have to do the white balance in camera. There is software for doing it offline. PhotoNinja does nicely for stills. Adobe does not work at all. I don't know about Lightroom, but it sounds like a "no." Link to comment
eye4invisible Posted August 29, 2018 Share Posted August 29, 2018 Yes, I use Nikon's own Capture NX-D for stills, export to TIFF, then finish tweaking in Lightroom. There may be some trick in Adobe Premiere for video, but I haven't discovered it yet. Link to comment
Andy Perrin Posted August 29, 2018 Share Posted August 29, 2018 Well your problem is not your camera anyway. You can probably get demo versions of various programs and try them out. I don’t have much interest in video so I haven’t got a program handy to play with it in. But definitely anything marketed as being for “color grading” which is the video term for color adjustments should have some control over white balance. Link to comment
Andrea B. Posted August 29, 2018 Author Share Posted August 29, 2018 Andy B, you can set an in-camera white balance in a Nikon which considerably lessens the red/magenta problem. Here are two examples. Crop, sharpening. (Although it doesn't look too sharp here, does it? Hmm.....) Crop, no edits. If you are interested, I'll write up the method. Link to comment
Jim Lloyd Posted August 29, 2018 Share Posted August 29, 2018 I have never had any success with in camera WB with my full spectrum Nikon D3200; tried various different approaches, lenses and filters. So would be interested to find out. I do white balance in Lightroom using a calibration file to get it roughly right and then the usual tools to get it right. This works pretty well. I think that other software produces a slightly better result, but the conviencence of staying within the Lr workflow is good with this method. If anyone want the calibration file contact me via personal message (I cant guarantee it will work for other cameras though) Re video I have found the tools in VLC player to be good and then I have been able to record the playback using tools provided with my graphics card. Not ideal, but I havent yet found a good solution for WB UV video. Link to comment

Andrea B. Posted August 29, 2018 Author Share Posted August 29, 2018 http://www.ultravioletphotography.com/content/index.php/topic/2209-crazy-white-balance-trick-for-converted-full-spectrum-nikon-dslrs/ So as it happens, I had already written up the procedure for creating a more useful in-camera WB for converted Nikons. Try it and let me know if it is useful to you. I've found it to be very useful, but it may not meet everyone's needs? I did some re-writing of that topic to clarify the procedure and to try to clean up the terminology. (You can comment at the end of the linked article, please.) Link to comment
