Clamp
In: Effects/adjustments
Description
The Clamp filter clamps values to defined limits.
It is used either directly on a fill layer to limit specific aspects of a material, or on a mask to constrain values to a given range.
NOTE
When used on a fill layer or as a passthrough for color information, the clamp affects each color channel individually. So, if a given pixel has a color of (R 0, G 0.5, B 1.0), and is clamped to 0.5, the resulting color of that pixel will be (R 0, G 0.5, B 0.5). This is because the Blue channel had a high enough value to be clamped, but the other channels didn’t. This means that the Clamp filter can change the hue of colored content.
If you do not want to modify hue, other filters such as Levels, may be a better choice.
