The Local Focus effect layer applies an area of interest highlight by softening the edges of your image. Add a local focus layer by clicking the Local Focus icon on the Effects tab of the toolbar, then adjust the selected local focus layer in the Localized Focus Properties panel.
You can use the local focus layer to subtly draw attention to a particular area on the canvas.
The local focus layer is controlled by a pair of overlapping circles on the canvas which share the same center.

Click inside a circle and drag the mouse to position the focus point.
Click and drag a circle's edge to resize that circle.
