Three quarters of the way through Amour, immediately after the terrifying moment when Georges slaps Anne, Haneke shows 6 paintings, each for about 8 seconds. Repeat viewings confirm that each is a gallery-lit closeup of (part of) one of the paintings from Georges's and Anne's apartment. Here are Amour's gallery-lit closeups (in Haneke's order) together with how we see them in the apartment.
The sequence begins and ends with paintings we see in the bedroom. We don't encounter the third painting in situ, in the living room, until the very end of the film.
