Documentary: When the cinema grew up - milestones of film technology

The ARTE documentary "When the cinema grew up - milestones of film technology" tells the highly interesting story of the evolution of film technology - especially of course the (analogue) film camera. It&s nice to see how technical innovations have always had an impact on visual language - for example, how the images changed when the initially stationary camera became a gently moving one, then later a liberated one. And the filmed images changed significantly when a viewfinder was available to the cameramen for the first time and they could see the exact image that the camera took - completely new image compositions became possible. And also the innovations Dolly, Kamerakran and Steadicam led to new pictures.
