Serious question, one I realize that the answer might be obvious. However, I will risk the fool to ask it.
As cameras have become so high definition, 16k some of them, is there a risk in watching an eclipse from the high end cameras or is there now some risk in using them to watch an eclipse through?
Zero risk.
Neither the light from the camera video display nor from any other playback device replicates the serious portentous for eye damage inherent in the direct light of the Sun.
I should note that keeping an unfiltered camera pointed directly at the Sun — even during the eclipse — will focus the sunlight on the CCD powerfully enough to torch it.
The camera needs a lens filter to attenuate the light and protect the CCD that the image is being recorded on.
Lens innards tend to melt with an eclipse filter
My 35mm camera has a movable screen on the back, so last eclipse I could point camera at the sun and view on the screen to take a picture. My guess is that looking through the camera directly at the sun would be a severely bad idea.
