This 1937 Nuremberg Rally shows Albert Speer’s “Cathedral of Light” effect. Spotlights were placed around the rally grounds pointed up. The effect was apparently stunning. When Speer first proposed the idea, the military opposed it, since it required the use of about every available spotlight. Speer’s counter-argument was that if the rest of the world saw such a profligate use of spotlights at the party rally, it would assume Germany had lots of them.
