This becomes so difficult for a lot of folks to grasp because when they look at the image on their computer it looks like what they tried to do in-camera. However none of that is saved in the raw file itself. In post unless you have a special app you can not save it then either. The raw file remains as it was simple plain 'raw' data.
I attached camera to light box and made 2 remote triggered photos. First with ALO enabled and second with ALO disabled in camera menus. I used one of the example programs that comes with libraw source code to make a viewable image of the raw data without any interpolation.
Notice that the histogram of the raw data is different when ALO setting is changed in the camera and nothing else is changed. The darker end of the histogram is changed the most.
Changing the ALO setting in the camera changes what raw file will be produced if any of the exposure settings are auto.
