How to Add a Gaussian BlurĀ in Photoshop



There are multiple ways to blur an image in Photoshop. Under the Filter > Blur menu there are several choices.

In this topic we'll demonstrate the Gaussian Blur. As you become comfortable with the Gaussian Blur, you may want to experiment with the other blur options that are available. The Gaussian Blur is pretty much the swiss army knife of Photoshop blurs.


Step One

Open an image in Photoshop (File > Open).

Step Two

With the image layer selected in the Layers panel, press Cmd/j (PC - Ctrl/j) to duplicate the layer.

Step Three

Name the upper layer Blur.

Step Four

Select the Blur layer and choose Filter > Blur > Gaussian Blur.

Step Five

Make sure that Preview is selected, then drag the slider and watch the image. Once you are satisfied, click OK and the blur is applied.

Step Six

Click the Blur layer in the Layers panel, press and hold Option (PC - Alt) and click the Add Layer Mask icon. The lower layer is revealed because the mask is black.

Step Seven

Select the Brush tool (b key), choose a large soft edged low opacity brush and set the Foreground Color to white.

Step Eight

Click the mask, then paint the mask to expose the Blur layer.

Gaussian Blur is One of Many Blurs

In addition to Gaussian Blur, you can use this technique with any of the blurs in the Filter menu.
