We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
of course, but excellently done. The excellence of the Edison pictures without doubt proved a stimulus to the rapid development of the art, far more than any contribution in mechanical design or new methods, as was later demonstrated when the courts held that the .Edison patents and re-issues were anticipated and invalid.
Among the early English workers were FrieseGreene and Mr. Evans who exhibited a camera before the Bath Photo Society, February 25, 1890, and in 1895 were working on a projector, work which was concurrent with the work of the L u m i e r e Brothers in France. The Lumiere camera was also used as a projector, however, and as such came to America in 1897,
The American Biograph, built by Herman Castler in 1896 was one of the very best of the projectors of these early development years. He worked on the theory that the larger the frame the sharper the definition on the screen because of the less enlargement required. This machine used 234'' width of film. The film, unperforated, was advanced through the projector by the griping action of mutilated cylinders which contacted for only a fourth of a revolution. The resultant screen picture was excellent, but like all the other mechanisms employing film differing from the generally accepted standard, had its day, played its part and dropped from sight.
In 1890, I began work on mechanisms for recording and reproducing motion. Two systems were developed side by side; one employed intermittent motion at the picture aperture, the other continuous motion. Cameras were first made, in which film was used, split to width in the dark from Kodak film bought in local photographic shops. These pieces were spliced into strips, sometimes twenty-one feet long, if I was lucky. Prints were made from negatives exposed in the cameras — usually in the continuous motion camera, for it made the steadiest pictures, though projection was mostly in the intermittent machine which had no interrupting shutter and therefore gave most illumination.
