The term “blackout” originally comes from the theater world and refers to an abrupt switching off of the spotlights, which was either used as a dramaturgical effect to emphasize a punchline or simply helped when arranging a scene or changing the scenery. It’s no surprise that it was later adapted for the spaces of the so-called “Lichtspiele” (in German, a synonym for movie theatre). What does it mean when the background is no longer visible? What does a background erasure mean compared to a free-form select of the foreground? And is there a complete erasure of the background at all, or are traces always left behind that can at least be guessed at? – M.A.
