Blur Pane

The Blur pane contains the controls for adjusting the type, amount and appearance of the blur. These settings are global and effect the blur across the entire image and all of the FocusBugs share these settings.

Reset: The Reset button resets all of the Blur pane settings to their defaults.

Version: The version pop-up selects the type of blur, Version 1 from FocalPoint 1 and version 2, the new blur algorithm for FocalPoint 2.

Lens: The lens pop-up contains settings that simulate popular lenses and their bokeh.

Amount: The amount slider is key, it controls the amount of blur for the image. The larger the amount, the softer the bokeh will appear and the larger the highlights will appear.

Low Amount
High Amount

Optic Quality: This slider varies the density of the aperture.
At the normal position of zero the aperture will have a hard edged shape.
At a lower setting, the aperture comes hollow and the shape of the highlights will have a softer center.
If the optic quality is raised the outer edge of the aperture becomes softer and the appearance of highlights in the background becomes softer.
Lower Quality
Normal Quality
Higher Quality

Aperture: This pop-up sets the number of blades in the aperture. The larger the number of blades, the more round the aperture and the highlights in the bokeh.

3-sided Aperture
6-side Aperture

Curvature: This slider sets the curvature of the aperture blades.
At the default setting of zero each blade has a straight edge.
As the curvature increases, the aperture shape becomes more round and smooth. A high curvature settings will look more like a fast, large aperture lens.
As it decreases the blades become concave and create a more geometric, even star shape. While this doesn't happen in real lenses it can create interesting shapes in the bokeh.
Low Curvature
Normal Curvature
High Curvature

Rotation:This slider is used to rotate the shape of the aperture.
