How to Focus a Camera on One Thing & Blur Out the Background
Advanced digital cameras include the ability to modify aperture priority. (digital camera 6 image by Harvey Hudson from

Single-lens reflex cameras, better known as SLRs, can focus on a single object in a picture and blur out the background. In order to achieve this effect, you need to use the aperture priority mode in your digital camera's settings. By lowering the aperture level, the camera's lens opens more and it will focus on the close-up object while blurring the background of the photo.

  1. 1

    Turn on your digital camera and use the mode dial to switch to Aperture Priority mode. On most models, this is represented as "AV" or "A" on the mode dial.

  2. 2

    Lower the aperture setting by using your camera's screen interface or the main dial above the camera's shutter button. The aperture setting is represented by the letter "f" followed by a number. You should lower your aperture setting to at least f/8.

  3. 3

    Position the object or person you are photographing no more than 10 feet away from the camera.

  4. 4

    Hold down the shutter button slightly to allow the camera to focus on the object or person. Most models will display a square around the focus area.

  5. 5

    Press down on the shutter button all the way to take the photograph. When the image is processed, the object or person will be in focus and the background will be blurred.
