How to Blur Parts of a Picture

By Derek King

Advanced photography often involves using different tricks with the camera and / or software to create professional-quality images. One often used photography effect is the ability to blur. The blur effect allows the image to focus on the subject by removing sharpness and clarity to other parts of the photo. This effect is often used in portraits of people and other important subjects. Use a digital camera or photo-editing software to add the blur effect to the image in a few simple steps.

Things You'll Need

  • Photo editing software
  • Digital camera with manual mode

Photo Editing Software

Step 1

Open any installed or web-based photo-editing software. Adobe Photoshop, Piknik or Picassa are photo-editing applications that include the blur effect. Click the option entitled "Open" to search for an image. Select the image and click "Open" to open the image within the application.

Step 2

Select a tool that is used to select a portion of the image. In most photo-editing applications, the tool is entitled "lasso," "marquee," "magic wand," "selection" or something similar. Click and drag around the parts of the picture that you would like to be blurred. Repeat the process several times until the picture is properly selected.

Step 3

Choose the blur option from the photo-editing software's effects toolbox. In the options pane, adjust the level of blur for the particular section of the picture. If required, click "OK," "Save" or something similar to save the effect onto the image. Repeat the Step 2 and 3 for additional portions of the image. Once finished, Click "File" and then "Save" to save the image and its new effects.

From a Camera

Step 1

Fill the camera's frame (viewed through the viewfinder or the LCD screen) with the subject. Set the camera to its "Manual" or "Aperature mode. Focus on a central object within the subject. With people and animals, for example, focus on the eyes.

Step 2

Zoom in on the subject using the camera's external lens (or a digital camera's digital and / or optical zoom lens). Stand as close to the subject as possible to create a shallow depth of field.

Step 3

Press down on the shutter button repeatedly to shoot a series of blurred images. Adjust the lens and the distance away from the subject to have varying degrees of blurriness.
