Many photographers do not understand depth of field, usually because they use an automatic focus camera that automatically selects this range for them. The depth of field shows the degree of the scene that will be in focus. Knowing use a camera's depth of field can greatly improve your photography skills.
Instructions
1. Choose the subject matter. If wanting to focus on a specific subject use a smaller depth of field, while expanding depth of field is a great way to shoot a landscape so the viewer can see the entire scene.
2. Select the camera's aperture. The depth of field is increased by stopping down the aperture. For example, f/8 has a larger depth of field than f/2.8. Remember, the lower the number of the aperture, the bigger the opening. The closer to the subject, the smaller the depth of field must be in order for the subject to be in focus.
3. Use a telephoto lens to create a blurred background. Zoom in on the subject and this should create a short depth of field for the desired effect. Don't be afraid to experiment. Remember a faster shutter speed will stop action while a slow shutter speed will blur action.
4. Use the camera's aperture priority mode if available. This allows you to control the depth of field while letting the camera select the appropriate shutter speed, removing some guesswork.
5. Keep a notebook and record preferred camera settings. Referring back to previously good shots will help with consistency and build a reputation as being a good photographer. Keeping a computer folder of pictures and settings is a good way to reference past work.
