Bokeh Image Node

The Bokeh Image node generates a special input image for use with the Bokeh Blur filter node.

The Bokeh Image node is designed to create a reference image which simulates optical parameters such as aperture shape and lens distortions which have important impacts on bokeh in real cameras.

Inputs

This node has no input sockets.

Properties

The first three settings simulate the aperture of the camera.

Flaps: Sets an integer number of blades for the cameras iris diaphragm.
Angle: Gives these blades an angular offset relative to the image plane.
Rounding: Sets the curvature of the blades with (0 to 1) from straight to bringing them to a perfect circle.
Catadioptric: Provides a type of distortion found in mirror lenses and some telescopes. This can be useful to produce a visual complex bokeh.
Lens Shift: Introduces chromatic aberration into the blur such as would be caused by a tilt-shift lens.

Outputs

Image: The generated bokeh image.

Example

In the example below the Bokeh Image is used to define the shape of the bokeh for the Bokeh Blur node.
