The Greene-Rudge-Evans device was a box film camera which, it was claimed, could be converted into a projector. By this time celluloid film was available in England as well as in the United States and France. According to the February 28, 1890, _Photographic News_, the camera could take ten photographs a second. The Greene camera, measuring eight by nine by nine-and-a-quarter inches, could take 300 pictures, and a smaller model turned out by Evans, 100 pictures. The reviewer of 1890 wrote, “the object of it is to obtain consecutive pictures of things in motion which can afterwards be rapidly consecutively projected on a screen so as to reproduce, say, a street scene, with the horses, human beings, and other things moving as in nature.” Greene this same year claimed that his machine camera would have important military uses. In this he was farsighted, as the modern motion picture camera is an important instrument of military reconnaissance, record and instruction as World War II has so amply demonstrated. In the British _Journal of Photography_ for December 5, 1895, A. T. Story defended Greene’s priority of invention and claimed that Greene’s projection apparatus of 1889–90 was a success. That conclusion is not inescapable. There appears no concrete evidence that Greene-Rudge-Evans achieved screen projection, for it is obvious that had they done so it would have been widely acclaimed at the time. But they did make a camera and attempted a projector. The camera apparently was practical. Marey and others in France, Anschütz in Germany, Edison, and Wallace Goold Levison in Brooklyn and W. N. Jennings of the U. S. Weather Bureau in Chicago, among others, were making successful motion picture films at that time. Projection remained the great problem. In 1893 Greene obtained a patent on a device related to the Chronophotographe developed by John Varley, a member of the English landscape painting family. His projection idea included a loop formed by means of intermittent pressure on the film passing before the lens. Greene’s November 29, 1893, patent application, accepted exactly one year later, was “to produce by means of reflected light artificial scenery to take the place of the ordinary scenery or background.” It included “improvements in apparatus for exhibiting panoramic, dissolving or changing views and in the manufacture of slides for the use thereof.” From this it is clear that even as late as 1893 Greene’s idea was limited in scope and effectiveness. At this time Greene made some pictures in Hyde Park with a large portable camera. It was described as a camera and projector in one, but that combination, without many modifications, has never been entirely practical.
