The other short he showed was around how photography was invented but never took off until Reese, a photographer in NYC, thought 'If I could just show people the inside of these slums and the poor living conditions, we could get them help.' There was some crude, dangerous ways to take photos inside or in the dark, but Reese heard of some German engineers that created a small controlled explosion called BlitchLit (flashlight). Flash photography caught on when Reese's images of slums in NYC changed public opinion and triggered one of the greatest social reforms in US history (Roosevelt's New Deal), then sewers and indoor plumbing a decade later. He was recorded as saying "our party carried terror wherever it went" but at least he got the shot and changed history.
