Skinning around Aspen ColoradoAs for portrait work try placing your subjects in shaded natural structures (silhouette) like in between cliff walls, near water, under trees or even man-made objects like between buildings, in or around automobiles or near shiny or light-colored walls or other reflective surfaces. Use your surroundings, they're often free and uniquely original. Your subject can also block the direct sunlight giving them a star like quality. You might consider using either on or off-camera fill flash depending on your desired effect to further enhance your creation.

Notice other artists work, break it down and try to figure out how they used their light sources whether natural or artificial but have fun.
