This filter applies time-varying Radial Blur filter to the source and blends the result with the original. Blending modes allow you to blur, offset or shake only a specific channel, only light/dark objects and make many other effects. Click here to see variation controls in detail. Blended dynamic radial blur Opacity out of 0.0-2.0 range Parameters: Blur Type "Constant" mode represents the real spin/zoom blur effect while "Soft" adds subtle directional blur. One-Way variations add not only blur, but a visual motion also. Size Controls the blur power. Value of 1.0 sets the maximum blur, but you can enter in edit field values from -4.0 to 4.0 and get more blur, but with a slightly reduced quality. Negative values set opposite-direction blur for One-Way modes. Variation Controls blur power variations. Variation slider allows you to set blur power variations to 0.0 and vary only blur direction. Distribution Controls the blur distribution over the image. Higher values limit the blur power in the center. Direction Controls the blur direction. Value of 0.125 - spiral, 0.25 - spin blur. Variation Controls blur direction variations. You could have  random variatianis between radial, spiral and spin blur. Variation slider allows you to set blur direction variations to 0.0 and vary only other parameters. Center Controls the position of the blur center point. By keyframing the Center control, you can have the effect center track your subject's movement. Variation Blur center point variatons allow you to get more complex dynamic blurs or motions. Blend Mode Select blend mode. Almost all known blending modes are realized here. Opacity Controls the blend opacity. Value of 0.0 is equal to 0% opacity (base image) 1.0 is equal to 100% opacity (blended image). But while most effects stop here in Radial Blend you can get mix between blended and blurred image (values in range 1.0-2.0). Plus - you can enter in edit field values from -20.0 to 20.0 and get other unusial effects. Variation Time-varying blending opacity produce random fade between original, blended and/or blurred image, depending on Opacity value and Variation power. You have full control over Opacity variations - Random, Variation and Speed/Density controls. Variation edit field accept values from -10.0 to 10.0. In "Add" random mode or with a high variation values the resulting Opacity value can get out of 0.0-2.0 range and produce flash, negative and other unusual effects.
