Autumn is one of my favorite times to shoot because it’s one of the few times I’m not completely at the mercy of the landscape and the light. As I hike along a trail, I like to gather fallen leaves, looking for the most colorful. When I arrive at my shooting location, I strategically scatter them in order to enhance the scene.
This works particularly well for waterfalls and streams (sprinkle rocks with color), and intimate still lifes (add a splash of leaves to a shot of bracken ferns). Just make sure that your scattering looks natural—too many leaves facing color-side up are a dead giveaway that the scene has been arranged.
