How to blur the background of an image in a DSLR

A blurry background in your photos makes your subjects stand out more. This is common in mostly portraits.

You don’t need to be a professional to do this to your photos. You can get the same effect by following these easy steps.

What makes the background blurry?

There are four things which determine the amount of blur you will get in your photos.

⦁ The distance between the background and the subject.
The greater the distance between the background and the subject, the more blur you will get in the background.

⦁ The optical length of your lens.
The longer the optical length, the blurrier the background will be. For example, shooting at 120 mm will produce more blur than 50 mm.

⦁ Your aperture.
The wider your aperture is, the more blur you will get. For example, setting your aperture, at f2 will produce more blur than f9. The number of f stops you will get depend on the type of lens you have.

Note: The lower the number, the wider the aperture.

⦁ The distance between the camera and your subject.
The closer you are to your subject, the blurrier the background will be.

 

How to get a blurry background:

As seen above, there are quite a number of ways to get a blurry background in your photos.

You can use the widest aperture you have available. For kit lenses, this is usually f5.6, while zoom lenses go as far as f2.8. This means you can get more blur from a zoom lens, than a kit lens.

Another way to get a blurry background is to get as close as possible to your subject. Putting more distance between your subject and the background also helps.

 

Conclusion

As you can see it’s not difficult to get a blurry background in your photos. This is something everyone can do with ease.

Doing this with your portraits makes your subjects stand out more in. It also makes them look more professional.
