Silhouette images are an excellent way to bring simplicity with an artistic flare to your photographs. In his very helpful article, 7 Tips for Photographing Silhouettes, Steve Berardi shows you a handful of useful techniques that you might want to try on your next adventure.
I think a big part of being successful at this is training your eye to be on the lookout for potential silhouette compositions. Subjects that might be less than thrilling in midday light can be transformed into poignant images at sunset. For example, take a look at this Grab Shot by Thomas M. Loftus.
