The controls are independent, so switching to blue does not remove or eliminate any changes
made to red, green, or Master. The animation and adjustments made to each channel are
separate. This menu simply determines what controls to display.
Contrast
Contrast is the range of difference between the light to dark areas. Increasing the value of this
slider increases the contrast, pushing color from the midrange toward black and white.
Reducing the contrast causes the colors in the image to move toward midrange, reducing the
difference between the darkest and brightest pixels in the image.
Gain
The Gain slider is a multiplier of the pixel value. A gain of 1.2 makes a pixel that is R0.5 G0.5
B0.4 into R0.6 G0.6, B0.48 (i.e., 0.4 * 1.2 = 0.48), while leaving black pixels totally unaffected.
Gain affects higher values more than it affects lower values, so the effect is strongest in the
midrange and top range of the image.
Lift
While Gain scales the color values around black, Lift scales the color values around white. The
pixel values are multiplied by the value of this control. A Lift of 0.5 makes a pixel that is R0.0
G0.0 B0.0 into R0.5 G0.5, B0.5, while leaving white pixels totally unaffected. Lift affects lower
values more than it affects higher values, so the effect is strongest in the midrange and low
range of the image.
Gamma
Values higher than 1.0 raise the Gamma (mid gray), whereas lower values decrease it. The effect
of this node is not linear, and existing black or white points are not affected at all. Pure gray
colors are affected the most.
Brightness
The value of the Brightness slider is added to the value of each pixel in your image. This
control’s effect on an image is linear, so the effect is applied identically to all pixels
despite value.
