This is Kodak Linagraph Shelburst film, originally developed for military use in recording aerial shell explosions, or at least for photographing objects against a bright sky (UFOs anyone?)
I am blown away by both the film and camera. These shots came out better than many others from more “real” cameras.
This particular roll was hand loaded into a Kodak Max HQ disposable camera by Adam Paul and was stand developed for 30 minutes with HC-110.
