I am glad to present you all my latest project: clight.
Clight will set your screen backlight level by capturing frames from webcam and computing ambient brightness; it can manage your screen gamma temperature too.
It uses geoclue2 to retrieve user location, and will compute sunrise/sunset times to set gamma.
It depends on a Bus interface i developed together with it, Clightd.
Clightd is responsible of setting/getting screen brightness, capture frames from webcam and returning their average brightness, and setting/getting gamma.
As it uses libudev to get/set backlight/get video device, it is much less prone to mistakes than "fopen/fscanf/fprintf", and safer.
Both softwares are distributed with a GPL license.
For more informations, please refer to both projects READMEs.
I hope someone will find them interesting and useful!
One thing - does clight support ICC color profiles? My screen is harshly blue without the correct profile applied. Redshift normally simply overrides your profile; it recently added support for a "preserve" option, which applies the desired color temperature as a function of the current profile, but unfortunately this makes the transform relative, and also not symmetrical. Turning the temp down by 1000K and then up by 1000K causes a loss in brightness.
It does not, i'm sorry.
Let me know if it feels better with clight compared to redshift though; may be different algorithms lead to different (hopefully better) results!
