Using Gaussian Blur – to blur background

Request

I have an image of a flower that is entirely in focus. I would like to blur the background to

make the flower stand out.

Response

A portion of the image can be blurred using the Gaussian Blur feature, followed by the

Selection Gradient or Brush, making the flower stand out.

Before

The background in this image is

not as blurred as expected.

After

While the foreground remains unchanged,

the background is blurred to make the main

flower stand out.

Procedures

STEP 1: Open an image

This is a close-up shot of two flowers. Background blurring will be increased to emphasize

the yellow flower in the foreground.

STEP 2: Blur the entire image

Select Gaussian Blur… from the Focus submenu in the Adjust menu.

In the Gaussian Blur dialog, set Radius to 30 px , and Opacity to 100% .

Click OK to apply the Gaussian Blur.

The entire image is blurred.

A Gaussian Blur step is added to the Edit List.
