Instance Property

maximumCircleOfConfusion

The maximum diameter, in millimeters on the imaging plane, at which light from a point source should appear in an image rendered using the camera.

Declaration

var maximumCircleOfConfusion: Float { get set }

Discussion

In a physically based camera simulation, the size of out-of-focus highlights that appear in images seen by the camera—commonly called bokeh—is a function of other camera properties, such as focal length, pupil aperture, sensor size, and distance to the subject. However, it can be useful for aesthetic reasons to limit the size of such highlights.

The default maximum circle of confusion is 0.05 mm.
