One way to create beautiful portrait images is through the use of a shallow depth of field. This shallow depth of field is important to your portraits because it will blur the background and have the viewer focus more on the person. This focusing on just the person can create great portraits no matter where the image is shot. And with that said, this post will show you a few different ways to achieve shallow depth of field in your portraits.
If you are not into photography or you do not want to learn how to take advantage of all the features of your DSLR , but you still want to take some decent portraits, I suggest you shoot on portrait mode. On the Canon DSLRs they will have a wheel on the top of the camera and one of the choices is a picture of a head. If you set your camera to this setting you will be in portrait mode and this setting will allow the camera to choose the correct settings for a portrait by making the aperture large (Smaller f number). This large aperture will make the depth of field smaller and this smaller aperture means that the background will be blurred.
Aperture Priority is the setting on the top wheel of a DSLR that is an AV. When you change your camera to this setting it makes the camera partially automatically decided the settings. What this means is that the camera will decided what settings will give you a nice exposure depending on the aperture that you decided to choose. Also remember when trying to get a shallow depth of field you will want a large aperture (Smaller f number). And this is a great 0ption to practice how to achieve a shallow depth of field because you can try many different apertures to figure out what aperture you prefer for portraits.
The lens that you use to shoot portraits will largely affect how shallow you can make the depth of field. The reason for this is that many cheap lenses do not have a very large aperture. This means that if you are shooting with a Canon EF-S 18-55 f/3.5-5.6 the largest aperture that this lens can produce is a 3.5 which is not that amazing. And even be able to shoot at this 3.5 aperture you will have to have your zoom set at the 18mm. Because when you use a zoom lens, the more you zoom in the smaller the aperture will be, so if I were shooting this 18-55mm lens zoomed all the way in at 55mm the largest aperture I could possibly have is a 5.6 aperture which will not allow much blur. So if you are really wanting to get into portrait photography I recommend you do some research on what lens is in your price range that will have a large aperture. But, if you are only going to shoot portraits I recommend that you also take a look into prime lenses because you will lose the zoom option but you will get a very good aperture and nice piece of glass for a considerably cheaper price.
