Here is tip #2…when photographing outdoor nature shots, experiment with the background. These pictures were taken on the same shoot. The above shot is set in flower mode, to slightly blur the background.
This one was shot in standard mode, but I moved low enough on the ground to capture the blue sky behind the daffodil. With flowers, it is always worth trying to capture the sky when it is bright outside. Remember…these are all with a simple point and shoot. Most cameras can provide interesting shots when set up well.
