Apple's tech specs for the Thunderbolt Display merely lists a:
Built-in FaceTime HD camera with microphone
I've not been able to find what the maximum possible resolution is. I say maximum possible because Photo Booth takes 4:3 pictures, where Quicktime Player's video recording can take what I believe is a full frame, 16:10 (or 16:9) video.
What is the maximum possible resolution image and/or video that a Thunderbolt Display's built-in webcam can take?
