Why does a light cast on a surface look dimmer when a much intense light is cast upon it?
Can you be a little more specific? Are you talking about the difference in intensity between a light source and the reflected light from a surface, or is there more than 1 light source?
I shined a light on a wall,for example.It looks OK.Then I shined another light on that wall exactly on that place.Now,the previous light looks more dim.Why?
That's the way your brain works. In some part, it bases the level of contrast off of the darkest and brightest areas in view.
