Along with many other photographers, I have found that cameras that limit your creative options can, in the end, enhance your eye for unique compositions. One of the best things I ever did for developing my creative vision was to spend a few months only using a film camera with 50mm lens. Pinhole photography takes this to an entirely new level.
For anyone into experimental photography, I highly encourage you to read Coomes' article and view some of the great images. You may even want to try it yourself!
