!!! 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
|
|
The main purpose of the Gamma (GMA) function is to compensate for the non-linear characteristics of the sensor.
|
|
GMA converts the pixel values according to the Gamma curve to compensate the sensor output under different light strengths.
|
|
The non-linear gamma curve is approximately constructed with different linear functions. Raw gamma compensates the
|
|
image in the RAW domain.
