"When shooting outdoors, frontlighting (sun behind the photographer) is most commonly used and the least interesting direction of light for your images. It works well for showing great detail on the surface of your subject, such as flowers blossoms, but sidelighting is a much better light to use whenever feasible. Sidelighting adds depth impact to your photos, whether your subject is a pinecone, sand dune ripples, a vast forested landscape, or a bustling cityscape. The most dramatic is backlighting, or shooting “against the light.” This technique is difficult to master, but worth it. Backlighting can be used to create silhouettes of the subjects in the foreground (often people) with wonderful results.
