Radial Blend filter blurs an image and blends the
result with the original. Thus you can add only subtle radial accent to
your image instead of full radial blur.
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 set 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.
Distribution
Controls
the
blur distribution over the image. Higher values limit the blur's
power in the center.
Direction
Controls
the
blur direction. Value of 0.125 - spiral, 0.25 - spin blur.
Center
Controls
the
position of the blur center point. By keyframing the Center
control, you can have the effect's center track your subject's movement.
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.
Blending
modes
allow you to blur only a specific channel, to get light rays and many
other effects.
With
some blending modes or by entering
in
opacity edit field values out of 0.0-2.0 range you get new, sometimes
very unusual effects.
