Scrolling through Erich Hartmann’s work on Magnum’s site, this shot from 1984 stopped me in my tracks. Simply titled Pair of shoes on deck, Caribbean, it’s both wonderfully calm and really damn harrowing. There’s so little detail, nothing to imply what may lie beyond the boundaries on the frame – where are they, where have they gone – so the mood is entirely down to whatever the reader brings to it, like some kind of Rorschach test.
