Apply filters

Select a layer that contains content you want to change.

Go to the menu bar and choose Filter > Filter Gallery.

Try the different filters and adjust their settings for the desired result.

Experiment with adding multiple filters in the Filter Gallery and changing their stacking
order.

Click OK to close the Filter Gallery and apply the filters you chose. You can also filter after you create a selection to apply filters to only the selected area.

Select a layer that contains content you want to blur, like a background.

Choose Filter > Convert for Smart Filters. Click OK. This converts the selected layer into a
layer that will support re-editable filters.

With the same layer selected, choose Filter > Blur > Gaussian Blur.

In the Gaussian Blur dialog box, adjust the Radius control until you’re happy with the amount of blur in the live preview. Click OK to apply the Gaussian Blur filter.

Note the Smart Filter that’s attached to your image layer in the Layers panel. This allows you to flexibly edit the filter settings. To do that, double-click the Gaussian Blur Smart Filter in the Layers panel, make a change in the Gaussian Blur dialog box that reopens, and click OK.

Save the image in Photoshop (PSD) format to retain the Smart Filter layer.
