The picture with Hailey and Alyssa is an example of depth. I used foreground, middle ground, and background, as my technique to take this picture. I had Hailey close to the photo, and she was in the foreground. Alyssa was in the middle ground, and the top of the stairs was in the background. As the picture leads you to the background it gets more blurry. There is a lot of space in this picture, creating a large depth of field.
