Hi, I would like to know if anybody can recomend webcam that is capable of tracking face movements in very low light conditions, and when I say very low light conditions I mean: My studio is pitch dark with very dim warm light eminating from the edges of the floor where it meets the walls kind of like at the show when they turn of the lights; that's about all the light that room gets when I play and the light emanating from 3 L.E.D monitors directly into my face. i don't even know if there is anything capable of doing a good track under those conditions. please advice, thanks!
