I've done that. In my office I have a 27" Mac from 2011. I keep it around as a 32-bit machine, and I decided one day to try using it as a video conferencing computer, because it has the biggest screen out of everything I have. The camera, on its default settings, makes me look like I have a skin disease. It's really horrible. But Macs from that era could have their video stream intercepted and tweaked by third party systems, so I desaturated it to black-and-white.
