@shadorne It’s obvious that you’ve never visited a network television control room.The high-end ones have 10-20 monitors of the same brand, same model and have the same power supplies. The image values of the monitors drift all the time. The chief engineer is responsible for keeping them calibrated according to standardized SMPTE broadcast settings. This enables the producer, the director and the lighting designer to confirm what they’re recording.
A multi-camera television show such as a sitcom has 3 or 4 cameras. They are all the same brand, same model, same lenses and have the same power supplies. The Technical Director (TD) is responsible for ’shading’ the cameras. Shading is the industry term for calibrating the cameras. Very simply the image values for each camera shift. The TD matches them. When shooting bigger productions such as the Super Bowl, the Oscars or the World Series, both the Chief Engineer and TD are very busy people with up to 20 monitors and cameras to match.
The above illustrates that drifting occurs in two types of well designed, very expensive, high-end professional equipment. Respectfully, in spite of your 6200+ posts, you are not always correct.
