How Moving Pictures started
Seems this is indeed to first film (not movie maybe) ever taped - by French astronomer P.J.C. Janssen. Monsieur came up with the idea for a "revolver to shoot the individual". The huge and massive camera model used a Maltese cross-type mechanism ad could have been the basis (as similar) for the later development of movie cameras.
What has he captured?
A 5 second film with two transits of Venus, the one of 1874 in Japan, and that of 1882 at Oran, in Algeria. Many consider this as the first movie in history.
