I have read that it is not good to expose a camera sensor to the full brightness of the noon sun... is this true. Or any very bright light (eg welding arcs, HID headlights, etc) for that matter. Will it cause damage to the sensor? If that is true, I noticed that the GFI sensor is wide open to exposure through the lens always (there is nothing in front of the sensor when it isn't being used). So, IF bright light damages a sensor, could this damage happen even if you are not using the camera. Say, it is hanging around your neck on a strap without a lens cap and inadvertently pointing at an ARC welder welding on the bumper of a car with its HID headlight on with the noon sun in the background. I realize these are strange questions... and I'm not really concerned. Just curious. Are the sensors vulnerable to very bright light? PS: This sounds like it should be on Mythbusters.
