Entry 56

I've noticed that when a room has one light on and other light off I can see the differences in the amount of light present in the two areas when I look at a wall. The wall not illuminated by the first light is dark and there is a distinct edge/area where the rays of the light reach. However, without the wall I can't tell where the light ends it just gradually gets darker, there is no place on the floor like there is on the wall.
