Adobe Photoshop CS6 Top 100 Simplified Tips and Tricks by Lynette Kent

ALTER DEPTH OF FIELD with a digital blur
Photoshop CS6 introduces a new set of blurring filters
that can digitally create a shallow depth of field or a
tilt-shift lens effect. The new tool includes a Field Blur
tool, an Iris Blur tool, and a Tilt-Shift Blur tool to
create the effect on an in-focus image. The Tilt-Shift
Blur tool simulates the lens blur a photographer would
get when using a view camera or a tilt-shift lens. The
Iris Blur tool mimics a camera lens blur while allowing
you to control the shape and size. The Field Blur tool
allows you to apply an overall blur to the photograph
or to a selection with one pin setting. You can add
multiple pins, each with an increasing amount, to
create a gradient blur. You can even apply different
blur filters together for creative effects.
Because the new blur filters cannot be applied to a
Smart Object, you can protect the original file by
working on a duplicate Background layer. You can
then toggle the eye icon on the blurred layer to view
the before and after versions of your image.
