the end the year their
efforts had brought forward the critical breakthrough the
development motion pictures: the use perforated film
strip place the pictures revolving drum. moved
from fixing small photographs coating the drum with gelatine
containing silver salts.
Celluloid film strip was also manufactured Eastman's and the
first order for this improved film was made Dickson in
September 1889. soon Dickson found out
about these strips celluloid film coated with sensitive
emulsion, obtained some samples from John Carbutt of
Philadelphia. Here was the advantage wide information net that
could give the workers West Orange the benefit of
technological advances elsewhere. This moved the film steadily past the lens. Throughout 1889 they worked several machines
to take and show moving pictures. The thick sheets film were cut into strips and
the top side the strip was cut into the form teeth which
engaged ratchet.VI-35
experimenters, who joined the team when the need arose for
their skills. From then onwards the development film
technology was dependent the film makers producing finer

Dickson soon found that the microscopic photographs
affixed the drum were impracticable and began increase
the size, and improve the definition, the image. The most important contribution to
Dickson's work West Orange came from the manufacturers of
photographic film: John Carbutt Philadelphia, the Blair
Company Boston, and the Eastman Company Rochester, New
York
