Aperture
All of the photos in this set are mostly with a shallow depth of field, however the lockers and the rocks (without the large white one) are on a large depth of field. To control the depth of field in my pictures i changed the aperture in the camera. for the photos with a shallow depth of field i used f-stop f4, these photo includes the photo of he white rock, the tree, the stairs, and the floor. For the ones where i used a f-stop of f11 all parts of the photo are in focus, these photos are the leaves, the rocks, and the lockers. i believe the photos with the larger f-stop are better because i prefer the photos where only one object is in focus. you would use a shallow depth of field if you only wanted one part of your photo to be in focus. On the flip side, you would use a large depth of field if you wanted the whole scene of your picture to be in focus.
