This essay investigates time-lapse cinematography as a hybrid, intermedial practice. To interrogate practices of authorship, publication, copying, storage, and especially distribution, it recovers the history of The Embryonic Development of Drosophila melanogaster, a film made by Eric Lucey at the University of Edinburgh in 1956. An unusually rich archive makes it possible to recover uses and reuses of time-lapse footage in research, teaching, and other forms of communication.
