Radius: It is considered as ideal control for sharpening and blurring tasks. Its default value use to be 0.50 and it will never show any specific effect on your footage whereas if you raise the radius slider then blur can be increased. Generally, a softer setting is achieved t 6.00 level. If you lower down your radius then sharpness can be easily increased; its minimum value can be 0.00.
