How to blur part of a picture

Experiment with the different blur tools to see which one works to your advantage. For example, you can apply the Iris Blur effect if you want the resulting photo to be partly blurred with a distinctive focal point. Here’s how to blur only part of a picture in Photoshop:

1. Open a photo in Photoshop.

2. Navigate to Filter > Blur Gallery and select Iris Blur.

3. After opening Iris Blur, you’ll see a blur preview ring with a pin and several dots. The pin is the point where the image is sharp and clear; the further away you get, the blurrier the image becomes.

4. Click the center of the pin and drag it wherever you like.

5. Now you can adjust the area of your blur photo. Everything outside of the ring will have the maximum blur effect. You can drag the dots to modify the area: hover your mouse over a dot until the cursor changes to a curved double-ended arrow. Then you can rotate, drag, and adjust the shape to your liking.

8. Don’t forget to click OK or press Enter at the top of the Blur Gallery window. Save your project or export your image.
