Flickr user TigTab creates beautiful scenes by light painting with hand-cut stencils. For each shot, the camera is left open while she moves about the location, firing her flash through the stencils in various locations to add the individual items to the scene. Some photographs take up to four hours to create from start to finish.
You can find a tutorial on how she creates her stencils here.
