# Lift Gamma Gain
|
||
|
|
|
||
|
|
This effect allows you to perform three-way color grading. The **Lift Gamma Gain** trackballs follow the [ASC CDL](<https://en.wikipedia.org/wiki/ASC_CDL>) standard. When you adjust the position of the point on the trackball, it shifts the hue of the image towards that color in the given tonal range. Use the different trackballs to affect different ranges within the image. Adjust the slider under the trackball to offset the color lightness of that range.

## Using Lift Gamma Gain
|
||
|
|
|
||
|
|
**Lift Gamma Gain** uses the [Volume](Volumes.md) framework, so to enable and modify the lift, gamma, or gain of the render, you must add a **Lift Gamma Gain** override to a [Volume](Volumes.md) in your Scene. To add **Lift Gamma Gain** to a Volume:
|
||
|
|
|
||
|
|
1. In the Scene or Hierarchy view, select a GameObject that contains a Volume component to view it in the Inspector.
|
||
|
|
2. In the Inspector, navigate to **Add Override > Post-processing** and click on **Lift Gamma Gain**. URP now applies **Lift Gamma Gain** to any Camera this Volume affects.
