What does a neutral density filter do?

My favorite filter is a neutral density filter.  It simply allows the shooter to expand his/her exposure beyond what is normally possible is broad day light.

The two images below represent a shot of the same area at the same time of day.  Both are on a tripod with the same lens and camera.

The exposures however are completely different.

The first exposure is a “normal” image and exposure.  The later is an expanded exposure due to the 10 stop neutral density filter (actually a variable filter).

The first image exposure was an 1/8 of a second at f22.


The image below is at 8 seconds at f/22.
