Editing Kinescope (section)

=== Kinescope image ===

Kinescope CRTs intended for photographic use were coated with phosphors rich in blue and ultraviolet radiation. This permitted the use of [[Reversal film|positive type emulsions]] for photographing in spite of their slow film speeds. The brightness range of kinescope CRTs was about 1 to 30.{{Specify|reason=Units?|date=December 2023}}

Kinescope images were capable of great flexibility. The operator could make the CRT image brighter or darker, adjust contrast, width and height, rotate left, right or upside down, and positive or [[negative image]].

Since kinescope CRTs were able to produce a negative image, direct positive recordings could be made by simply photographing the negative image on the kinescope CRT. When making a negative film, in order for final prints to be in the correct emulsion position, the direction of the image was reversed on the television. This applied only when ''double system'' sound was used.
