Adjust Gains
Master gain changes the whites/high RGB values. You can use positive or negative values. Master black changes black/low RGB values. You can only input positive values for Master Black. Without changing the gain values, the SHIL gives you a raw image with too high of a contrast. That is, whites are too bright, and blacks are too dark. You need to adjust the mid-tone and black level to achieve a good calibration. To do this, it is recommended to at least raise the master black. Lowering the master gain will help achieve a more ideal mid-tone, but be careful, because color can start to lose saturation when you do.

8. When the light grey (white) and the dark grey are well balanced you can move on to applying corrections. How long the lights have been will affect the color balance. If the lights have gotten quite warm and everything looks even, then when the lights are 'cold' the blue channel will be lower than the others.
