Fun with long exposure

Taken in a soon to be developed area of Ottawa, this photograph was one of many attempts. Here you can see some friends "doing things to themselves" for no good reason.

How
Since there was almost no light out except for a dim pathway light and some highway light I was able to take a 10 second exposure. (the camera captured light for 10 seconds). for 5 seconds they would stand absolutely still and quickly move to another position for the remaining 5 seconds. Thus making it appear they are in the photograph twice.

Full View to see the expressions. Priceless.
