Want a Challenge? Challenge yourself with a 50/50 Photowalk. Arm yourself with a fast 50mm lens, and commit to taking a picture every 50 feet. It's a challenging exercise for a photowalk, and you'll learn a lot. A fixed focal length lens will cause you think and frame shots differently. Being forced to take a picture every 50 feet opens your eyes to see detail and really simulates your creative juices. You'll be surprised at the results. So get out there and shoot, and remember, pictures are made, not taken.
