For vivid colours, you can use the Pop Art mode. This will add saturation to reds, blues, greens and yellows, and is particularly useful for shooting flowers. It does a good job of shooting landmarks on clear, bright days, too. Check out the clouds in this scene, which really pop out of the sky. It was shot at f/10, 1/640th and ISO 200. We also used Live View and angled the screen so that we could take it from an elevated angle.
