I'm sure there would be some freeware out there that does this, but for all my research I've failed to find anything!
So what I want: a piece of software that uses the webcam to automatically adjust the screen brightness of my monitor (not my laptop's screen). I would like it to have some customization abilities so I can specify how frequently I want it to check the light and change screen brightness (rather than constantly being on). I would also like a smooth transition when changing the brightness, but this is a nice feature, not a strictly necessary one! This software must be free (I don't care if it's open source or just shareware)!
