The Depth Of Field Blur filter applies a blur gradient that can be used to simulate extreme depth of field and miniaturization effects, such as tilt shift.
This filter can be applied as a non-destructive, live filter.
The following settings can be adjusted on the vertical sliders:
Radius—controls intensity of the blur.
Vibrance—controls the color intensity of less saturated colors (a high value increases the 'model-like' effect).
Clarity—increases the local contrast and gives the appearance of increasing the sharpness of the image.The following settings can be adjusted on the context toolbar:
Split—enables the Before and After view. When toggled, it presents filter application side by side.
Apply—applies changes made.
Cancel—cancels changes made.The gradient stops determine the position and extent of the transition between the areas in sharp focus and those that are blurred.
The focus origin (A) defines the central point at which the image is kept completely in focus. Reposition the focus origin by dragging on the stop.
The inner lines (B) define the width of the area in focus. For the Tilt Shift mode these can be set independently by dragging each of the stops in turn. The Elliptical mode always matches the shape of the inner lines to the outer lines so that only the width can be specified.
The outer lines (C) define the end of the blur transition. For the Tilt Shift mode, these can be set independently by dragging each of the stops in turn. The Elliptical mode always sets the stops in pairs.
The transition areas (D) between the inner and outer lines are where the blurring gradually increases. The wider the lines, the more gradual the transition. The area on the outside of the lines has the filter applied at the full amount set by the Radius slider.
The angle of the filter can be changed by dragging the stops at an angle.
