When sunlight hits colorful fall foliage, it makes a stunning backdrop for your impromptu family portraits. The trick to getting the painterly background look that makes the subject pop off the background is to use a wide open aperture. The portrait here was taken at 70mm with an aperture setting of F/2.8. Focusing on the eyes, the background drops out due to the shallow depth of field into a painterly sparkle of fall colors. If your lens does not open to a fast aperture like F/2.8, use your telephoto lens at its maximum zoom, set the camera to aperture priority and choose the widest aperture opening (most likely F/5.6 or F/6.3) and step in a little bit closer. That combination will drop out the background for a similar look that makes a beautiful portrait suitable for framing and display on your mantle.
When you say “landscape” I’m sure the vision you have in your mind is a panorama of a sprawling field, distant mountains or grand canyons taken with a super wide angle setting on your zoom lens. However, telephoto zoom settings can also be used effectively for landscape photos. When you zoom in on the details of your landscape, you can bring out something special. Here, in Nikko, Japan, I captured the majesty of the not-quite peaked fall season by isolating a few brilliantly colored trees clustered together in the still mostly green landscape. The resulting picture says “fall” unlike the wide angle shot I could have taken. Next time you’re shooting landscapes, zoom in and see what interesting detail you can find: a single tree, a mountain peak, a reflection in the lake, and more. When you use the telephoto setting, you compress the distance between objects and achieve a flat, almost painterly 2-D effect.
