One of the benefits of the new interface that the Blur Gallery use is that you can work on one layer (in this case, adding a blur) yet still see all of your other layers while applying the filter. In addition, you can choose to show your Layers panel while in the Blur Gallery (Window > Layers) to change Opacity, Fill and Blend modes. When finished interacting with your layers, you can choose to hide the Layers panel (and any other panels that are showing), click and select “Reset Workspace” from the Blur Gallery workspace (in the upper right of the interface).
Will all blurs, you can:
• Hold the “H” key to temporarily hide the Blur interface (pins etc.).
• Tap the “P” key to toggle the preview on and off.
• Hold the “M” key to display the mask.
• Add as many blurs (even mix and match between Tilt Shift, Iris and Field) as needed to a layer, knowing that the multiple pins will create a single unified, intersecting mask).
• Use the option Save Mask to Channel to create an alpha channel.
• Vary the Selection Bleed to expand the blur into the selection. Note, you have to have created a selection before selecting the blur filters or this option will be unavailable.
Specific to the Tilt Shift blur:
• The area between the solid white lines has no blur applied. The distance between the solid and dashed while lines is the “transitional” area where the amount of blur is slowly added over the length of the transition. Beyond the dashed line, the specified blur amount is fully applied.
• Click-drag the solid white dots to rotate the angle of the blur, OR click-drag anywhere outside of the solid white lines to rotate the angle of the blur. Note: if you click, release the mouse and then drag you will add another blur – you must click and drag in one motion, without releasing the mouse between the click and the drag. Add the Shift key to constrain to 15 degree increments.
• Add distortion to the foreground of an image (or rotate the blur to favor the opposite direction). Or, choose Distort Symmetrically to apply distortion to both sides of the blur.
• Use the Focus slider (in the Options bar) to blur the center part of the Tilt Shift blur (if you want the whole layer to start slightly out of focus).
• The Blur Effects panel offers a various settings to customize a Bokah effect.
Specific to the Iris Blur:
• From the center pin to the “free-floating” solid white dots, no blur is applied. Between the solid dots and the solid white circle is the “transitional” area where the blur is applied over the length of the transition. Beyond the solid white circle, the blur is fully applied.
• Option + (Mac) | Alt +(Win) -drag the free-floating dots to move independently (thus making the transitional area asymmetrical).
• Drag the large square on the solid circle outwards to create a rectangular shape Iris blur.
• Drag the small white dots on the outer circle to rotate and/or to distort the circle to an oval.
• Use the Focus slider (in the Options bar) to blur the center part of the Iris Blur (if you want the whole layer to start slightly out of focus).
