HUD Controls
The HUD contains the same controls as the Inspector, with the exception of the mix
control.
Color Balance
Color balance generally refers to the overall tint of an image reflecting the color
temperature of the primary source of light. For example, sunlight is generally bluer
than interior tungsten light, which tends to be more orange. Although most film and
video is shot to make sure that the whites in an image are a true neutral white,
different film stocks and video color balance settings result in slight tints in the image.
Use this filter to adjust the color balance of an object by boosting or lowering the
individual amount of reds, greens, and blues in the shadows, midtones, and highlights
of an image. You can use this filter to correct for improper color balance, or to change
the color balance in an image for a stylized effect.
