So i went to Photo Booth today just to take a quick photo. Photo Booth launched but there was nothing appearing where it has the camera preview, just a black/blank screen. The green light on macbook was lit up showing the camera was on but nothing on the screen. I checked Console and found this "25/11/07 12:03:24 AM Photo Booth Using 8bit graphics" I've tried restarting, tried my iSight in iMovie and all the same results. I am running Leopard. Any ideas?
