Marco Lagemaat Posted October 17, 2021 Share Posted October 17, 2021 Yesterday I took the opportunity try my first IR's (and some full spectrum). And boy.... this is awesome. I'm quite satisfied. in particular the last IR from the firework. so crisp, so overwhelming. Nikon D70s, Prinz Galaxy 35mm 3.5, 200 iso, f/8, 8", fullspectrum; Nikon D70s, Prinz Galaxy 35mm 3.5, 200 iso, f/8, 30", fullspectrum; Nikon D70s, Prinz Galaxy 35mm 3.5, 200 iso, f/8, 8", fullspectrum; Nikon D70s, Prinz Galaxy 35mm 3.5, 200 iso, f/11, 2", ZWB3 (UG5) Nikon D70s, Prinz Galaxy 35mm 3.5, 200 iso, f/22, 2", 850nm Nikon D70s, Prinz Galaxy 35mm 3.5, 200 iso, f/22, 2", 850nm Link to comment
Doug A Posted October 17, 2021 Share Posted October 17, 2021 @Marco Lagemaatthese are really neat. Never thought of doing IR or FS of fireworks. Spectacular images. Thanks for sharing, Doug A Link to comment
colinbm Posted October 18, 2021 Share Posted October 18, 2021 What a beaut collection. Link to comment
dabateman Posted October 18, 2021 Share Posted October 18, 2021 I hope that wasn't a backyard display. The arcs are interesting in IR. This makes me wonder if multiple cameras are set up for visual, IR and UV with same shutter speed and focal length, what the trail differences would look like. You might even be able to see some really deep UV from fireworks depending on what color is used and whats being burnt. Link to comment
Cadmium Posted October 18, 2021 Share Posted October 18, 2021 All of these are very nice! Link to comment

You might even be able to see some really deep UV from fireworks depending on what color is used and whats being burnt. That is almost exactly what I thought. But I thought of three cameras and shoot them synced each with a different IR wavelength and then stack all the same color channels to one new RGB image and then (hopefully) see some color. But than you need small band pass filters. I guess. Link to comment
Andy Perrin Posted October 18, 2021 Share Posted October 18, 2021 I could do two channels at once with my stereo attachment. You can’t do IR and UV with same shutter speed directly though! Too many stops difference. You could find some kind of neutral density filter for IR maybe and reduce the brightness down to UV levels? Link to comment

Andy, Its fireworks at 2 second exposure time. It might be possible. I just don't have fireworks. I don't even have a magnesium road flare to test. But I am thinking it would be like that. We got enough UV off a candle, fireworks should be easier. Link to comment
Andy Perrin Posted October 18, 2021 Share Posted October 18, 2021 Haha no you are missing my point. It’s not that it’s too dim, it’s that the exposure is orders of magnitude different for UV and IR. If you record one properly, the other will be either all black or all white in a single image capture. There is more than enough light, it’s just the difference between the sensitivity to UV and IR that’s the problem. Link to comment

Yeah, I understand what you mean. But I meant only IR. So for example; All in sync: 720nm RGB -->, RRR (swap from 850nm, 950nm) --> making a new RGB 850nm RGB -->, GGG (swap from 720nm, 950nm)--> making a new RGB 950nm RGB -->. BBB (swap from 720nm, 850nm)--> making a new RGB Link to comment

Handy!! stereo I saw you're topic! Must be worth a try do. Link to comment
Andrea B. Posted October 20, 2021 Share Posted October 20, 2021 Marco, these are fantastic photos. I love seeing the Ferris Wheel patterns. And fireworks in IR really rock! Link to comment
microbat52 Posted November 12, 2021 Share Posted November 12, 2021 Ohhhh! Those IR fireworks are awesome! I need to take my IR camera out at night Link to comment
