Often we get stuck in a pattern of photographing things they way we usually see them. Looking down at kids (well they ARE short:), up at trees and buildings, down at flowers, etc.
One way to add interest to your photographs is to try to capture things/people/landscapes from a perspective you don't see everyday. For example, a hot-air balloon from above, a sailboat from on the top of its mast, someone from above...walking across a mosaic floor.
See if you can get out of the habit of just putting the camera to your eye and shooting everything at your own eye level. Get up on a chair, crawl on the floor, shoot up at something we normally look down to see. It's amazing how eye catching it is to see everyday things from a new perspective. Try it!
