I stand corrected. I tried for a fourth time, and apparently, after chmodding you need to wait for a minute or two. After that if you open the camera app, there is a black screen, exactly as you described.
EDIT - I still don't understand. The camera seems to be completely controlled by black magic. I have not recorded, but opening/closing the camera, then changing the permissions seems to allow you to continue using the camera app even with (0600).

Probably because the camera service was still running and has already opened the file before you change the permissions. Changing permissions doesn't affect existing file descriptors.
