Trade Tricks: The Selective Focus Technique
One of the challenges we face as photographers is making the subject stand out from its surroundings. An effective way to do this is to use the selective focus technique, which allows us to choose one part of the image to be sharp and in focus while making the rest out of focus. It's the opposite of getting a lot of depth of field. While this technique lets the viewer know what's important in the photo, it's also a way to make interesting compositions that can't be duplicated any other way.
