The origins of scientific cinematography. Part 1, The pioneers.

Dedicated to the astronomer, J. Janssen, the photographer Edward Muybridge and the physiologist E. Marey, this is a compilation of documentary film sequences intended for use in teaching. Arranged chronologically in six sections, it supports the thesis that cinematography had its roots in science. Among the sequences are Janssen's "photographic revolver" (1873/4), designed to record the transit of Venus in front of the Sun; Muybridge's development of serial photography of human and animal locomotion (1878-87); Marey's "photographic gun" (1882), his models of the "chronophotograph" (1882-93) and his first research films. The film is based on Virgilio Tosi's book "Il cinema di Lumiere"
