!!! Warning

This is an **Expert Parameter**! Only change it if you understand what it does!

After changing this parameter you need to update your reference image and alignment markers!

!!! Note

A higher gain means that the sensor has a greater response to light, but also makes sensor noise more visible.

This is used when **CamAgc** is on.

!!! Note

The **Gain** is an analog multiplier applied to the raw sensor data.<br>
The **Ceiling** is the maximum gain value that the sensor will use.
