How do you practise spotting better compositions?

[williamming005]

When you’re out with a camera, how do you train yourself to notice stronger compositions in ordinary places?

Do you use exercises such as sticking to one focal length, looking for a particular shape or colour, or photographing the same location in different light? I’d love to hear which exercises you’ve found useful.

Best start with a book on composition.
