Making an Unfocused Background Gradient

After applying the DOF Effect to a photo, the foreground will always be surrounded by an unfocused (blurred) background. This result is ideal most of the time. However, if there is an extended plane, such as the floor, ground or the table with the foreground object on it, the surrounding blurry background will be inadequate, because it creates a false impression of image depth.

The original photo without DOF effect

Everything excepts the foreground object is de-focused.

FaceFilter provides a Background Gradient feature so that the defocused background can be gradually from fully-blurred to none-blurred.

The gradual blur effect makes the depth of the photo more convincing.
