The video explains how brightness is perceived based on the amount of light passing through a given area. It highlights that the same amount of light appears brighter when emitted by a smaller object compared to a larger one, due to higher luminance.

What is the relationship between light emission and perceived brightness?

How is brightness perceived by our eyes?

What effect does the size of an object have on its perceived brightness?
