Boiling Metal Shot Backlit at 20kfps. 0dB Gain; 97° Shutter; f/32; 100mm.
Originally did a Black Calibration at 180°, later changed my mind to set it to 97° Shutter Angle just before shooting, but forgot to do another Black Calibration, so there now sadly is a visible line, but well. Lows are Boosted quite a bit in Editing from the DNGs to see what is going on, no denoising at all to preserve all detail contained in that Shot. An untouched DNG of that Clip is also uploaded here for everyone who wants to play with that.
I also made a Wide shot of another Sparkler, but at 5400fps; 0dB Gain; 219° Shutter, f/2.8; 100mm; also Uploaded here.
Both of these Shots give quite a bit of insight on how these Sparklers actually "work" or rather what is going on, and where the Sparkly Bits are Coming from.
Quality isnt Amazing, so i might need to re-shoot that at some point with the Exposure and Light dialed in a bit better. Dont know if i will do that however...
