Intentional camera movement can be fun for fall color images (among other things). Try using a slower shutter speed and panning the camera up or down, zooming the lens while shooting, or moving it in little circles. It's fun to experiment with this technique and every image turns out different.

Another fun subject that is fairly easy to find, reflections. You just need water! I like to look along lakes, streams, creeks and ponds during morning or evening light. Sometimes even just a puddle will work. If your subject is lit by the sun and you have contrasting colors it can make for a vibrant image and I love the painterly look. Of course this can be a lot of fun during fall colors!
