There's a range of light to dark you can see at once. Your eyes can adapt and move the whole range up and down, as can cameras. You're right that it takes time.

There's a range of light to dark you can see at once. Your eyes can adapt and move the whole range up and down, as can cameras. You're right that it takes time. But the width of the range at a given moment is wider on people than many cameras (sans post-processing). That's why this video is deceptive. Our eyes can see details in the light and dark at the same time better than cameras can. This (https://i.imgur.com/3u1kN7T.png https://i.imgur.com/3u1kN7T.png) is an example. The top picture has less detail in both the lightest and darkest portions than the bottom one. The human eye is reeeeally good at that.
