Using light painting with objects- still life- is different from making a portrait. People move. That can look really interesting. Dealing with the non moving, concrete "things" and all the surroundings is a good way of thinking about form, composition and shape. In still life, several artists influenced me very much as an art student, Cezanne, Morandi, Leger and Marsden Hartley especially. Here are some works made in my senior year. Still life -charcoal on paper from 1979.
When I make a still life with light painting, usually I selectively move some parts around nudging some object a little to distort its ordinariness- fishing around for some hoped for visual impact.
Below are some older light paintings.
