Depth of Field
Here, we experimented with depth of field. A shallow depth of field (as seen on the left, shot at f4), shows the foreground of the image in focus and the background is out of focus. On the right, there is a great depth of field (shot at f22). In this image, both the foregound and background are in focus.
Tilt Shift Miniatures
These pictures use a technique called tilt shift, making a picture of any scene look like a miniature scene.
