A four-lens turret was mounted ion the camera front, which facilitated the cameraman’s work and was necessary for the new focusing and framing system. They decided to adopt single plane film travel using a double chamber (compartment) metal magazines with screw-on compartment lids installed on top of the camera body. Finally and most important, an extremely precision mechanism was included which was considered one of the best in producing a steady image. A new way was found for focusing and precision framing through the taking lens. Wood was substituted by metal and ball bearings were applied to most parts. Its design discarded the handcrafted concept adopted until then and opted for stoutness and precision of the components. completed this series of revolutionary with and exceptional motion picture camera which radically changed the building concepts for this kind of equipment. The item was followed by their model D which became a classic the world over. It was a film printer working on the continuous printing method by means of a special sprocket, where the negative and the positive met emulsion side-to-emulsion side in front of an aperture adjustable to modify the light intensity. The third instrument designed and built by this firm appeared in 1911 and it continued their standards of high precision and ingenuity. It made perforations on negatives and positives with different characteristics in sizes, all of which proved to be extremely efficient. The machine effected eight perforations simultaneously per frame, with a pitch of 0.1870 in., its efficiency widely improving upon all similar equipment. They continued building equipment in 1910, first a film perforator which made history since it set a standard as to dimensions of perforations adopted by the whole industry. Only a few units of this model were sold, but it was a valuable experience for the future. In 1909, the new firm manufactured its first motion picture camera like most of the cameras of the time, its body was wooden, covered with leather, but its movement included the novelty of a fixed pilot pin. The first instrument they built was a projector called Kinochrome with the outstanding feature of being one of the first, to have a Geneva cross unit rotating to adjust the framing. This firm’s previous first steps were repairing and adjusting cameras. Howell, an engineer, formed a small company in Chicago for the purpose of manufacturing, hiring, and jobbing equipment for the motion picture industry. Bell, a projectionist and mechanic, and Albert S. Motion Picture Photography: A History, 1891-1960, By H. These enterprising young men have so many orders booked ahead for their different machines that they are compelled to increase their plant by taking another floor of the same building. Capital is invested every day in the erection of new theaters and in the promotion of of new branches of the industry.Īn example is the great prosperity of Bell & Howell, of 90 Illinois street (217 W. Cinematography is still in its infancy and will last several generations to come.
