Document the drama of the changing leaves with a series of photos that captures a single tree at different stages. The technique of time-lapse photography is particularly effective at speeding up imperceptibly slow processes like the blooming of a flower or the subtle blush of fall foliage. How you choose to use the technique depends on the sophistication of your photo equipment and the time you want to commit to the project.
The simplest form of time-lapse is to take three or four photos of the same tree at the same time of day in similar lighting and frame the photos in a series. To make this work, position yourself on a spot that's easy to find again, like a tree stump or a large rock.
For a true time-lapse effect, you will need to take hundreds of pictures from the same exact spot and string them together in a short digital movie. You'll need a tripod and preferably a digital camera with an interval setting that can automatically snap a picture every few hours [source: Elliott]. Since a movie requires 24 individual frames per second, you would need to capture 240 shots for a 10-second movie. Assuming that a tree takes 60 days to go from fully green to fully red, that means four pictures a day. For more detailed tutorials on time-lapse photography, visit the Digital Photography School.
