What was the first professional camera to shoot LOG gamma? In: Cameras Posted February 6, 2018 5 hours ago, jonpais said: No mention of pushing or pulling of film like the old days. From the Sony technical document you claim there is "no mention of pushing and pulling": 3.1 Changing the Sensitivity (Push Process / Pull Process) The most common method is to adjust the MASTER GAIN of the camera as shown in Table 4. The image contrast that appears on camera viewfinders and the on-set displays will remain consistent, hence it is easier to monitor 3.1.2 Push Process Increasing camera gain will improve camera sensitivity but will increase the camera noise floor. When extra dynamic range is required, the exposure value should be defined according to the light meter readings as in film. 3.1.3 Pull Process Reducing the camera gain will improve the signal to noise ratio performance. This technique is suited for blue/green screen effects shots where pulling a clean key is of prime importance. It should be noted that the camera dynamic range will be reduced. Chart 1.

Thanks @IronFilm!
