Let’s say this is a tribute to one of my favorite Jeff Wall’s photographs (The Flooded Grave, 1998-2000). Wall described the “event” of that picture as “a moment in a cemetery”. The viewer might imagine a walk on a rainy day. He or she stops before a flooded hole and gazes into it and for some reason imagines the ocean bottom. We see the instant of that fantasy, and in another instant it will be gone (from London Tate Gallery exhibition info).
