Parameters in the Inspector
Contrast: Sets the amount of contrast to be applied to the object.
Pivot: Sets the point around which the contrast is adjusted. The point of contrast
adjustment is the level that is displayed if Contrast is set to 0.
Clip Color Values: Turns clipping on and off. Clipping prevents color adjustments from
forcing color values out of the allowable digital range. Clipping can prevent illegal signal
levels in clips that are output to video. This pop-up menu has four options:
None: No clipping occurs.
At White: Any color channel exceeding the maximum value of 1 is clipped to 1.
At Black: Any color channel falling below the minimum value of 0 is clipped to 0.
At Black and White: All color channels are clipped to a minimum of 0 and a maximum
of 1.
Mix: Sets the percentage of the original image to be blended with the color-corrected
image.
HUD Controls
The HUD contains the following controls: Contrast, Pivot, and Clip Color Values.
Gamma
Adjusts the relative distribution of brightness in the midtones of an image, without
adjusting the white and black points. The perceived result is to brighten and darken the
areas of medium brightness in an image, while leaving the highlights and shadows
untouched. This avoids a washed-out effect.
