Why are solar eclipse camera filters necessary

340 viewsOtherPhysics

I’m told that to photograph the solar eclipse with my smartphone I will need a filter to put in front of my camera to prevent damage to the sensor. My understanding, and maybe this is where I’m wrong, is that a camera that doesn’t have a telephoto lens can shoot pictures of the sun on a normal day without a filter. If that’s true what makes a solar eclipse different? It would seem to be like the more the sun gets blocked, the less energy makes it to the sensor, the safer it is for the electronics. Does it have to do with exposure time due to a darker scene?

On a normal day it is just as bad for your camera to take a picture pointed directly at the sun, it’s just that on a normal day one generally doesn’t point their camera directly at the sun.
