I always cover the cameras with a sticker (on all devices except my phone). I have never noticed any openings for the LED and the ambient light sensor on my MacBook. Are they behind the plastic? I am just curious. I deleted photobooth, and FaceTime, so I will never have a need for the camera. I only see it a a potential security risk. I do use the camera on my phone, and I still own a Cannon EOS. i have never used the camera on my iPad. I do not see the point.
