Shallow depth of field means eradicating the background from being focused and concentrating mainly on the subject. Well here is a set of tutorials which allows you to acquire shallow depth of focus:
- Select portrait mode from the list of modes available in your camera menu. This will automatically set a shallow depth of field for you. For users who are unaware from adjusting the aperture manually can select this mode as it automatically sets a large aperture for you making the area under focus smaller.
- If you have a little knowledge of aperture range of the lens, you can select the aperture priority mode as it allows you to select the aperture and the other adjustments are automatically done by the camera system. Just a quick recap of aperture: large aperture (low F stops) creates shallow depth of field. This semi auto mode defocuses the background and concentrates on the main subject.
- One easy yet expensive solution is getting a new lens other than the kit lens. If you are serious about portrait photography it is recommended that you must avoid using the kit lens (18-55mm). Better lenses will provide you with more flexible and better aperture range. One of such lenses available for canon users is the Canon 50mm f/1.8 lens and if you are a Nikon user you can go for the Nikkor 35mm f/1.8G DX Lens. Both of these lenses offer large aperture and hence creates a shallow depth of field. Such lenses also create high quality images in low lightning situations.
