When shooting shows where background is darker than foreground subject,
cheaper cameras have a darker background than the more professional ones,
even though the foreground subject is at the same brightness.

This seems to imply they have different gamma response. But shouldn't all
video cameras have the same standard gamma, whatever it may be? Or do the
makers of cheaper camera lower the gamma to hide the video noise in darker
area?

The effect is particularly noticeable when editing together clips from the
same shoot from a consumer camera and a pro camera.
