Some studios use a master CCU that can successively control all cameras. You typically also see red and blue gain , pedestal controls , and a cable length setting , which must be set to the length of the cables used on each camera. If this is out of adjustment you will see a slight jump in video to the left or right as you switch from one camera to another. Color Reproduction Is Subjective E ven though you can quickly notice color changes between cameras, color is quite subjective. In fact, when it comes to judging color the human eye can be easily fooled.
Sunlight contains a roughly equal mixture of all colors of light.
On the Kelvin scale the lower the color temperature the redder the light is, and the higher the color temperature, the bluer the color is. The photo is intentionally dark to emphasize this difference. As an example, if you look at a white piece of paper in sunlight, you should have no trouble verifying that it is white. When you take the same piece of white paper inside under the illumination of a normal incandescent light, it still looks white. But, by any scientific measure, the paper seen under a standard light bulb is now reflecting much more light yellow.
