'Margaret Mead and Gregory Bateson's 1936-1939 field trip to study the
Balinese and the Iatmul was a landmark in the history of
visual anthropology.'

'Mead and Bateson worked out a precise system for recording field data in Bali. They synchronized their
watches, along with their Balinese secretary, Madé Kalér. While Bateson took still and motion picture film of
events, Mead and Madé Kalér took notes, recording the time of events at frequent intervals. They noted when
photographs were taken with "LEICAS" or "L," and when motion picture film was taken with "CINE" or "C."'

Bateson took this 16mm film of the making
of wajangs [Shadow Puppets] in Bali
