(From this OnePlus 3/3T thread on 4PDA.)
- Made a "Night mode" with the ability to manually adjust its parameters, in my opinion the result gives better than NightSight Gcam 6.x, do not forget to use exposure compensation for the situation (+1 or +2). Also added an automatic restart of the camera when changing parameters that require restarting.
- It is possible to lower the saturation settings of the night mode to ~ 0.2 and 0.8, in general, you should test it.
This is based on the old Google Camera 3.2. Don't expect any of the modern features.
