The first commercial system of Prizma was similar to Kinemacolor in that the camera took alternating frames of red-orange and blue-green colors through color filters placed within the camera's shutter. Colors in full saturation are hardly within the scope of this process. Yellow is not in evidence in the current Prizma films, although a wide variety of warm tones are apparent, ranging from chestnut-brown to a deep red-orange. We have not noticed anything approaching a true green in any of the subjects so far exhibited, although this is probably by reason of the fact that no prominent greens existed in the subjects photographed. The results by this process are characterized by extreme delicacy of color, and subdued shades are most admirably rendered.… The blue-green element of the projecting filter appears to favor the blue rather than the green, and as a result, skies and water are well reproduced. The disk used in projection consisted mainly of two colors, red-orange and blue-green, adapted to the four-color process by the superimposition of two small magenta filters over one of the red sectors and two similar blue filters over one of the blue-green sectors. The film was photographed at 26 to 32 frames per second, and projected at 32 frame/s. The colors were red, yellow, green, and blue, with overlapping wavelengths to prevent pulsating effects on the screen with vivid colors. Prizma gave a demonstration of color motion pictures in 1917 that used an additive four-color process, using a disk of four filters acting on a single strip of panchromatic film in the camera. However, Kelley eventually transformed Prizma into a bi-pack color system that itself became the predecessor for future color processes such as Multicolor and Cinecolor. Initially, it was a two-color additive color system, similar to its predecessor, Kinemacolor. The Prizma Color system was a color motion picture process, invented in 1913 by William Van Doren Kelley and Charles Raleigh. "The Scanjig fits perfectly with me striving for a minimalist office.William Van Doren Kelley and his invention, the Prizma color camera. "The beauty of the ScanJig is that it can hold anything from a smart phone to a tablet." Visually impaired user "A great accessory for our iPhone/iPad fleet management solution" Maureen Quintanar, bulk trucking professional, Los Angeles Again, many thanks for this." Kay Malmquist, KNFB Reader user. "This is a really great and useful tool and I am definitely going to be using it a lot. Thanks for developing such a useful item." Denis Nelson, Moultrie, GA "It works perfectly with both the KNFB Reader and Text Grabber" - "I couldn't be happier with it. This product immediately let me setup, focus, and hit the shutter button one-handed. I purchased the ScanJig because I have use of only one hand and my bank's app requires me to photograph checks as I deposit them. I use blue tooth shutter release to further eliminate movement caused by my shaky hands. It is perfect! No blurs, no shadows of my hands or phone from ceiling lights. The ScanJig - "takes a lot of the frustration out of reading". I like to support people who take the time to make a quality product and actually listen to their customers." Richard Turner I have explored several other scanning stands and have found your device to be the most intuitive and user friendly. I use a ScanJig with an IPhone and the KNFB Reader.
