I just found this in one of the extras to an old 1930's movie (on DVD) and thought it might be of some interest to some of you. It's a short newsreel about Harold Edgerton, the inventor of high speed photography. Even though it isn't exclusively "photography" (they show a lot of high speed cine stuff), I find it's still worth taking a close look at it as it is quite interesting.
