Unlike the blur options in previous versions of Photoshop, the Blur Gallery filters are designed specifically to produce a selective focus effect. The Blur Gallery is comprised of three filters; Field Blur, Iris Blur and Tilt-Shift. In addition there are a separate set of Blur Effects that let you create specular highlights mimicking the circular bokeh effect produced by lenses. In this article I’ll show you how these tools work and hopefully inspire you to start using them on your own
You can find the new blur tools by going to Filter>Blur. Selecting one of the top three options (highlighted in red) will open the new Blur Gallery.
The Blur Gallery opens in a full size window that temporarily replaces your regular workspace. Panels along the right give you access to all three of the blur filters as well as bokeh adjustments.
Because the blur filters are applied directly to the image pixels, rather than as a layer adjustment, I strongly recommend that you first duplicate the background layer of your image before applying any of these filters. If your image already contains multiple layers, select the topmost layer and merge the visible layers into a new additional layer by pressing Command + Shift + Option + E (Ctrl + Shift + Alt + E on Windows). Then go to Filter>Blur and choose either Field Blur, Iris Blur or Tilt-Shift.) This will open the Blur Gallery.
