Washington DC DPA Instructor Dana Bowden offers 5 tips on photographing in the autumn time:

Tip #1: COMPLIMENTARY COLORS often exemplify the beautiful fall colors as shown in the image of bright scarlet leaves against a deep blue sky.

Tip #2: A DRAMATIC SKY with a silhouette of the dark leaves is also quite dramatic.

Tip #3: TRY A DIFFERENT ANGLE, like these tall trees from the ground up.
.

Tip #4: THE SNOW CAPPED MOUNTAINS IN THE BACKDROP create a depth of field and emphasize the fall colors of the trees.

Tip #5: USE A TELEPHOTO LENS to get a close up of the leaves and bring out their color with the simple but intense blue sky.
