When you think of aperture choice and depth of field in landscape photography, you likely trend toward using narrow apertures for a wide depth of field. And while that is certainly a great way to approach images, you can create unique photos by using a narrow depth of field, which is what this excellent video explores.
Coming to you from Alister Benn with Expressive Photography, this informative video takes a look at using a narrow depth of field in landscape photography. Traditionally, given the subject matter, landscape photographers opt for a wide depth of field to maximize sharpness and get as much of the scene in focus as possible. However, using a narrow depth of field can be a fantastic way to focus your viewer's attention on a specific spot in the photo and to bring out a smaller subject in a clean, unfussy way. It is also a great method for getting more images out of a scene and creating unique photos that stand apart from the sort of landscapes we are used to looking at. Check out the video above for the full rundown from Benn.
