To: Use:
Blue, Alpha, Luma and None. When None is selected, the image
is blurred as if the Modulation Channel had a constant value of
1. Note that this behavior is different than muting the entire
modulated blur. This is an aid for trying to figure out what the
various parts of the tool contribute.
To offset the selected modulation channel before it affects the
modulated blur. The offset is subtracted from the channel. The Offset
output image will be in focus where the modulation channel is
equal to the modulation offset; it will be progressively blurrier for
values of the modulation channel above and below the modulation
image. When the modulation tab is displayed and the Player is in
Display Tool output mode, selecting the offset picker tool then
clicking anywhere in the player will set the Offset parameter to
the value of the selected modulation channel under the pointer.
This is useful for selecting the in-focus object in a scene.
