Andy Perrin Posted July 18, 2019 Share Posted July 18, 2019 Same settings and equipment as the other flowers in this series, with exceptions noted below. UV2mm UG11 + 1.75mm S8612 (Convoy S2+)Saturation strongly increased VisibleBG38 2mm and DB850 filter (645-405nm) NIR-Red-Green (550-645nm + 835-875nm)Tiffen#12 + DB850 filter, and my usual algorithm for making the IRG, described in the DB850 filter thread NIRHoya R72 + DB850 filter (835-875nm) SWIR(1500-1600nm, made by the panorama method and reduced for higher resolution) UVIVF under Convoy S2+ and using BG38 2mm and DB850 filters --- Comments:The SWIR looks a lot like the visible but with a lighter disk in this one, enough that I got scared and decided to check if my filter was leaking. However when I stacked it with my hard-coated premium Thorlabs 1200nm long pass (guaranteed >OD5), it looked the same, so I guess it just looks similar by coincidence. If you look at the bottom left of the flower, there is a tiny splash of water on a petal, so you can see that the water, although dark, isn't inky when it's just a thin layer like that. This morning the disk florets had started to open up, and they are white in the SWIR 1500-1600nm band: Link to comment
Cadmium Posted July 19, 2019 Share Posted July 19, 2019 Andi, I especially like the Tiffen #12 + DB850 stack flower, and also the UVIVF. Link to comment
dabateman Posted July 19, 2019 Share Posted July 19, 2019 Great flower images.You have much less dust than I do. That is what I seem to see in my UVIVF images. Maybe thats why I prefer UVIIRF, skips my dust. Link to comment
Cadmium Posted July 19, 2019 Share Posted July 19, 2019 Andy, What illumination for the Tiffen #12 + DB850 stack shot? Link to comment
