The motion picture benefitted immeasurably from the
expertise gained the telegraph and phonograph work. The addition, and subsequent modification, a
Geneva stop mechanism was major step developing reliable
camera and projector.
(See Sidebar 6-3, "The Black Maria.")
Dickson had achieved some success taking pictures
rapidly the film strip, but there were still mechanical
problems the film feed mechanism which caused unsteady,
flickering image. Another area which the mechanics made
an important contribution was the synchronization film and
shutter. was men like these who altered the feed provide
a more positive movement that would not shift the film around
at high speeds. The mechanics who worked with Dickson,
chiefly William Heise, Henry Kayser, and the Ott brothers, had
years experience the telegraph industry and were expert
at the mechanics moving tape rapidly and exactly past an
aperture.

special studio was built make movies with the kinetograph. The kinetograph was fitted with a
start and stop switch and counter that showed amount film
used. The kinetograph was the truly original part the motion
picture system because although many had devised viewing
machines, none had produced camera like this before
