Film on reels
Film was a material on which movies and photographs were recorded.
In 2269, Captain John Christopher guessed that Air Defense Command would process the film he'd used to take images of USS Enterprise quickly. (TOS: "Tomorrow is Yesterday")
Also that year, reels of film flew in the air, produced by the Megan prosecutor as a visualization of history. (TAS: "The Magicks of Megas-Tu")
