Painting with light is a great deal of fun. You can do it anywhere. A darkened room will work, as will the night itself. These two shots were taken at a recent night photo workshop I gave on Point Reyes.
Improvisation is the key. The lights along the fence above was created by a slow dance with two performers and two colored lights; the striped light coming down the stairs (below) was a flashing iPhone.
