why looking at welding is very dangerous for your eyes but a camera can film it just fine.

387 viewsOtherTechnology

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?

I would like to add on top of what everyone else said, there were issues maybe a decade ago with powerful lights like welders and lasers indeed damaging cameras. The whole difference is that our eyes are sensitive and can be easily damaged by UV light (which welding lets a lot out) and the sensors in cameras aren’t super sensitive.

If you’re ever looking at old camera footage and there’s random small green splotches, that’s usually damage to the sensors lol, I used to watch a lot of laser video guys/electric engineers dealing with a LOT of power, and half of them always them. Nowadays it’s still possible but they are a bit more resistant.

If you’re talking about in the sense of why you can watch the video and be fine, it’s because the camera can only record so much brightness. You can look at footage of the sun just fine. The camera only can record up to a limit, and whatever you’re watching it on can only be as bright as the screen brightness.
