Adjusting the Gain and Offset
 
 
 

You can boost the colours in an image by increasing the Gain and Offset values. The Colour Corrector multiplies the pixel colour values by the Gain and then adds the Offset value. The resulting colour values are clipped at the maximum value of 255 in 8-bit mode, or 4095 in 12-bit mode.

You can also reduce the colours in the image by decreasing the Gain and Offset values. The resulting colour values are clipped at the minimum value of 0.

Gain is expressed as a percentage value. The default value of 100% has no effect on the image since the colour values are multiplied by 1.

NoteYou can adjust the Gain for individual ranges, or across all ranges simultaneously (by using the Gain fields in the Global controls). However, changes in gain mostly affect the highlights in the image.

To boost or reduce the colours in the image:

  1. Select the range you want to modify.
  2. Enter a value in the Gain field for the colour channel you want to modify.
  3. Enter a value in the Offset field for the channel you want to modify.
  4. Click Process to apply the changes to the clip.
