to all those recommending better lighting: nobody sits in a dark or unlit room when using a webcam. we shouldn't need to buy more crap at extra expense and space just to make something which should work work. it's the cheap components in the cameras which are the problem. I don't understand why this seems to be the norm, it reminds me of laptops being sold with crappy resolution screens even though the underlying hardware was fully capable of outputting higher. they still exist actually
it will take years before good quality webcams become the norm. we are only just starting to see them with built in IR sensors in mid to higher end models
