Tilt Shift Blur
Photoshop CS6 Tutorial
How to Add Tilt-Shift Blur in Photoshop
Photoshop CS6 added three new blur options; Field Blur, Iris Blur and Tilt-Shift Blur. The three blur variations are meant to simulate a camera lens and can be accessed from a single Blur Tools panel. They can either be applied individually or a combination of the three.
Open an image in Photoshop (File > Open).
With the image layer selected in the Layers panel, choose Filter > Blur > Tilt-Shift Blur.
In the Blur Tools panel, the Tilt-Shift Blur section should automatically open. Adjust the slider and increase the blur. Notice that the solid lines denote the sharp area and the blur zone is indicated with the dashed lines.
Click-drag the pin to move it to a new location. You can drag the lines to adjust the blur.
To change the blur setting for a pin, click the pin and drag the circle around the pin. You can also select the pin and change the value in the Blur Tools panel.
To turn the Tilt-Shift Blur effect on and off, click the checkbox. A quick way to delete all of the pins is to click the Remove All Pins icon
To add a Field Blur or Iris Blur, click the triangle to next to the corresponding blur option. You can add multiple blurs to a single image.
In the Blur Effects panel, you can add Bokeh to enhance the blurry areas of the image.
Once you are satisfied, click OK and the blur is applied.
Creating Miniatures with Tilt-Shirt Blur
The Tilt-Shift Blur is great for creating a scene that looks like a model railroad set because of the shallow depth of field.
Temporarily Hiding Pins
To hide the pins so you can get a better view of your image, press Cmd/h (PC - Ctrl/h). Press Cmd/h (PC - Ctrl /h) a second time bo make the pins reappear. If you forget the keyboard shortcut, you can always choose View > Extras.
