I have come across several articles in which the camera settings for shooting video are explained. If the camera does not provide RAW footage it is recommended to set Contrast, Brightness and Saturation as low as possible, and also change the midtones curve adjusting lowlights to high and highlights to low, in order to get an image as flat as possible.
This way it is claimed that the footage can be easily post-produced.
I wonder if that is a valid way, or if it is better to adjust as desired the image on camera.
Any thoughts would be appreciated.
