In my junior classes I had read- Light itself cannot be seen but it can cause other objects to be seen!
Seems like this picture defies that statement.
Still, I cannot decide that which detailing is more dominant-
The details of the path of the sunlight or
The details of the piece of wood the light is passing through or
The details of the room which is glowing in the magnificence of the sunlight
Decide for yourself and let me know!
