Description
— Uncheck the Gamma checkbox.
 When you enable gamma correction, the text box and graphic show the
factor applied.
 If you run preview video while adjusting the filter, you see your adjustment
effects interactively.
 You can use one of three methods to adjust the gamma correction value:
(1) Directly enter text in the numeric text box.
(2) Click [+] and [-].
(3) Select Signal field (NTSC, PAL, or SECAM) from the options list.
 Gamma correction applies to all filters and all output pins on each device.
The gamma correction can be different for different physical devices.
NOTE: These values represent the inverses of the gamma bias that
you applied at the video source per the video standard so the
resulting video becomes gamma-neutral.
