Great Depth of Field Rule of Thumb
A rule of thumb for achieving great depth of field in landscape photography is:
- Use an f/stop ranging from f/11 to f/16.
- The closer the foreground is to the front of your lens, the higher the f/number should be.
For example, if the closest thing in the picture is about 4 feet away from the front of your lens, you can usually get away with an aperture of f/11 and get a great depth of field. If the closest thing in the picture is about 2 feet away from the front of your lens, you probably need to change to f/16.
Define Wide Angle vs. Telephoto
- Wide angle: anything wider than 35 mm-e. Or wider than 24mm on a APS-C sensor size camera. A wider lens takes in a larger angle of view. That means that when you look through the lens you see more of the scene. A 14mm lens is wider than a 24mm lens. The shorter the focal length the wider the lens. Tangent: if you’re just learning to shoot wide consider using a focal length of 24mm-e (16mm on APS-C). It’s wide, but not too wide. Learning on anything wider is more difficult, because it sees too much of the scene. That makes composition much more difficult.
- Telephoto: anything longer than 60mm-e. Or longer than 40mm on a APS-C sensor size camera. As you increase the number of millimeters of a lens, your lens sees less; a 200mm lens is longer and you see a narrower view than a 100mm lens. Basically, you zoom in.
