I customized a luminosity curve for my surface rt, just edit the registry keys.
Download extract and run the attached .reg file and confirm the insertion of the Keys, then reboot the system.
Alert to make a backup of the old keys if you want to restore the previous state.
This change is compatible with all windows 8 but I have tested only on the surface.
Adaptive brightness varies proportionally to the user manual brightness, I suggest to manually adjust the brightness bar to about 20%, if you place the bar at 0 the brightness will be minimal with no automatic adaptation.
Appreciated thanks

New version v2
New improved version.
Try it and tell me if it's okay.
In the zip you will find the normal version and one with more brightness in the dark
I suggest to manually adjust the brightness bar to about 25%

So you have a fix, that's great. But to what? You didn't state what the problem is. Neither did you way what you are doing differently over the default values. Why would me, or anybody else for that matter, want do download this?

In my surface the luminosity curve does not satisfy me.
The display seemed to have only three levels of brightness, setting an average value (ie on the desk in the room in the morning) adaptivity did not fit values ​​for low-light (night) and lots of light, that is to say the brightness in the dark was not a minimum making it annoying for the view and unnecessary consumption of battery, instead with shaded light levels brightness became easily maximum, with again a waste of battery.
This forced me to move often the brightness bar manually, but now with my calibration does not touch more because it adapts automatically to any light condition.
Also the adaptation of brightness occurred after 3 seconds by the change of light, whereas now changes instantly in 0,1 seconds (100ms).
