Often on TV or YouTube when I watch videos where someone welds something the light produced by the welder, while bright, doesn’t even seem to overwhelm the camera. The point is bright, but the surrounding area is still visible by the viewer.
On the other hand it is very dangerous to look at welding as a bystander because it can very much blind you.
So, what’s up with the light sensors on camera’s? Is it not possible for them to burn out? Especially the large sensors of professional cameras should be quite sensitive to a bright light like that right? Or are there special thingamajigs that prevent that?

The ELI5 version of this is that both eyes and cameras sense light and too much light can damage them, but eyes are much more delicate and their safe upper limit is much lower.
You can estimate how hot something is by sticking your finger in it, right? Or you could use a thermometer instead. If you stick your finger in boiling water, though, it’s gonna hurt even though the thermometer will be just fine. If you try to stick that thermometer in, say, molten metal, though, now it’s going to fail too.
There is *some* brightness level that in theory would fuck up your camera, but that limit is so high that it’s unlikely to come up without other things becoming a problem first.
