Entry 39

When light is shining though a blind the closer the surface it hits the clearer the blind shadows are. When shining on a table there are clear light and dark patterns but when the light has to travel all the way to the floor the shadows blur. The distance the light has to travel affects the type of shadows it produces. Is there a particular reason for this? I've notice that in the theater despite the criss-crossing wires the only things that cast shadows are the much larger beams. Why is the light able to fill in shadowed spaces as it travels further from its source?
