![]() Of course, when you’re changing your aperture, you’ll have to change your shutter speed with it to make up for a correctly-lit exposure. Simply by changing the aperture, you can change the blurriness of the foreground. Now you’ll get the most shallow DoF you can get with your lens. To achieve the blurry background, put your lens on the lowest f-stop number that is possible (meaning your lens will be wide open and receive a lot of light). They’re relatively low in price and can give you that look you want. Look for a 50mm prime lens with f/1.8 or f/2 apertures. You’ll benefit from a prime lens, as they’re generally cheaper and can offer much faster apertures than zooms. If you’re interested in making portraits with a blurry background, then I recommend that you buy a lens with a faster aperture. What we mean by this is that your lens may not be able to shoot at very big apertures (think of f/2, f/1.8 or f/1.4 for example) because kit lenses are usually relatively cheap and slow. If you’re just starting out and only have the kit lens of your camera, then it isn't likely that you'll be able to achieve super blurry backgrounds because your lens may not be ‘fast’ enough. However, it really depends on your lens how far you can go. By using a wide open aperture (low f-stop number), you can create a shallow DoF. The most important setting on your camera to keep in mind is the aperture. So how do you get those blurry backgrounds or foregrounds? There are a couple of ways to achieve this look.

When you see portrait photos with a very blurry background, they have mostly been taken by using a ‘shallow’ DoF. From this point, the field of focus starts and fades out into out-of-focus on both the front and back, depending on the factors mentioned above. When you use the focus on your camera (you’ll probably mostly use autofocus), the camera locks its focus on a single point. This field is different for every photo and depends on the properties of your lens, sensor and camera settings (mainly the aperture). It’s usually measured as a focus plane that doesn’t simply cut off on both ends but has a smooth transition from sharp to unsharp (or 'in-focus' to ‘out-of-focus’).

When using a fast aperture and photographing people standing close to the camera, it’s important to focus on the eyes to ensure that they’re in sharp focus. For example, if you’re photographing a person standing a few meters away using a lens like the Canon 85mm f/1.8 lens with the aperture wide open, only a small part of their face will be within the depth of field, meaning that maybe only their eyes will be in sharp focus and the rest of their face will be softly blurred. The farther away you are from your subject, the greater the depth of field will appear to be in your photo. ![]() With the subject’s eyes in sharp focus, areas that are outside the field of focus appear softer, so wrinkles and other skin blemishes are less noticeable. Since the field of focus is very narrow when using a fast aperture setting, a shallow depth of field is often preferred for things like portrait photography. By shooting “wide open” using a fast aperture, distracting foreground and background elements can become soft blurs that no longer divert attention away from the subject of your photo. A shallow depth of field can help to draw attention to the area of the photo that is in sharp focus.
