Richard S. brought up the question some time ago and I worked out the
math for a source that was finite i.e. not a point source. The math
shows essentilly no change when you are very close to a large source.
Then as you move farther away intensity varies at one over distance.
Finally at very large distances (say, tens times the size of the source) the
intensity goes as one over the distance squared. Apparently this is what
some people on the list have observed.
BTW there is one light source you can use and ignore the inverse
square law i.e. the sun ;-) (unless, of course you work for NASA).
