Pick a wider aperture, around f/2.8 or f/5.6, to isolate your subject from its surroundings. This will help create visual contrast between the sharp subject and the background, which will be softer and more abstract. This also adds tension between the real and the unreal, providing you with an image that’s more dynamic and expressive. Experiment with different subjects and backgrounds and get creative with your choices. Pay close attention to your subject and make sure that you have the desired amount of the subject in focus when using a wide aperture.
3. Make fall color the secondary subject
The temptation is for you to make the primary subject all about the fall colors. Find other primary subjects such as streams and waterfalls that are accented by the fall colors, to make images that have more depth and complexity. Although the color may attract your eye to the scene, ask yourself what the subject might be other than color.
