The quest to produce motion
pictures in realistic colors began the instant that the first hand
cranked cine camera turned. A variety of assorted methods achieved varying
degrees of technical and commercial success prior to the introduction of
three strip full color Technicolor® in 1934.
Becky Sharp (1935),
the three-color feature film that eroded the widespread commercial viability
of all other methods of color photography for nearly 20 years. The picture
was produced by Pioneer Pictures in collaboration with Technicolor Corporation in an effort to demonstrate
to studios that had tired of imperfect and complex systems that films
could be photographed in full color. But our story goes back beyond the
dazzling success of 3-strip Technicolor, which is covered later in this
site. This story begins four decades earlier...
Explanation of Successive Exposure
Versus Simultaneous Exposure Systems
The facts about the color image seen at left are muddied with the passage of time. In fact, they were muddied by 1925 when the film was described in a book entitled A Million And One Nights: a history of the motion picture through 1925 by Terry Ramsaye. Ramsaye goes into great detail explaining that the frame was part of a fifty second sequence shot by Urban and Smith in England in July, 1906 and was the birth of Kinemacolor, a successful two color process. However, the image was restored by me from a photo of a three color negative. Other sources state that the image dates back to 1901, which might be close to the truth. Urban and Smith began their research with three primary colors (red, blue, and yellow*), based on the work of Englishman Edward R. Turner, whose original British patent had been issued in 1899. The three color system was deemed virtually unworkable, and the registration in this photo would seem to bear that out. Following Turner's untimely death, Urban and Smith began work using two colors, blue-green and red-orange.
As you can see, the color fidelity appears remarkably good, but the image suffers from extreme fringing. This tells us that the camera that took the picture did not expose all the color records simultaneously. Static items, such as the ladders and background are relatively free of artifacts. Moving objects, the two children and the swing, are fringed because movement takes place during the interval between successive exposures.
Systems that used either multiple lenses to achieve simultaneous exposures or single lenses taking successive exposures will always suffer from fringes and/or parallax error.
One of the reasons for the success of the early Technicolor systems was that they used single lenses and simultaneous exposures.
* The primary colors, red, blue, and yellow, as described above, may be an error on author Ramsaye's part. Most probably the colors were red, blue, and green.- MBH
