In this tutorial, I explain the differences between the three new blurs in the Blur Gallery that have been added to Photoshop CS6; Field Blur, Iris Blur, Tilt-Shift. Plus, if you’re running Photoshop CS6 13.1, available to Creative Cloud members, you can now apply these blurs to Smart Objects!
The New Blurs
Field Blur works great when you want to focus on an area of your photo, such as the foreground or background. A field blur was added to the image below in order to focus more on the mountains.
Iris Blur can be used to focus in on an individual object, leaving the rest of the scene blurry. In the image below, an Iris Blur was added to keep the golf ball in focus, and blur out the background.
Tilt-Shift blurs can be added in order to give the impression that your subjects are part of a miniaturized scene, as seen in the image below.
