Software to auto adjust brightness of screen(s) from webcam

"i was looking for the same thing, for now i only found this, doesn't work with camera, but with time, at least

"I ended up with running brightness adjustment every hour (using http://sven.killig.de/BLUntrl/) via the following autohotkey script:

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
#Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.

Loop
{
Run, D:\autohotkey\BLUntrl.exe
Sleep, 10000
Send, {Esc}
Sleep, 3600000
}
Return

This solution seems to work fine with f.lux.

Calvin's application from previous post is great, but it alters color balance on my monitors."
