Abstract: During the evolution of cinematography there has been a constant demand for increased light from a single source. Early attempts to meet this demand were made by improvements in lamp projection optics and by increasing both size and power input of the light source.1In recent years a great deal of work has been done toward increasing the intrinsic brilliancy of the high-intensity carbon-arc source, This has resulted in a series of carbons known as super-high-intensity carbons.2, 3This paper will describe the requirements of the motion picture industry which brought about the production of these super-high-intensity carbons and will cover details of the development and design of carbon-arc lamps to burn them. The use of super-high-intensity carbon-arc units in motion picture studios may properly be divided into (a) Process background projection;4(b) Set lighting.1
