Hello kramtwo,
Thank you for using Apple Support Communities. It's my understanding that your MacBook Pro camera doesn't work with FaceTime and Photo Booth. You've come to the right place! I'm happy to help.
If you haven't already, make sure that your Mac has the latest software version.
How to update the software on your Mac
If the issue persists, try testing the issue in safe mode. Starting in safe mode allows your Mac to run certain checks, remove caches, and prevent login items from automatically launching. This can isolate possible third party issues. Use the steps and information in the link below for assistance with safe mode:

If the camera is still unavailable, test the issue in a newly created administrator user account. This will help determine if the issue is user specific or system wide.

Have a nice day!
