spinners. Any pixels in the mask that are of the selected channel and between
the Min and Max values will have the Blur effect applied. This is useful for
blurring selected portions of a scene such as a winter morning as seen through

Channel Selects a channel that the Blur effect will be applied to. After
selecting a particular channel, use the minimum and maximum spinners to
determine the value a mask pixel must have in order to have the effect applied
to it.
Brighten Brightens the portions of the image that the Blur effect is applied
to.
Blend Blends the Map Mask Blur effect with the original rendered image.
Min The minimum value (RGB, Alpha, or Luminance) a pixel must have in
order to have the Blur effect applied to it.
Max The maximum value (RGB, Alpha, or Luminance) a pixel can have for
the Blur effect to be applied to it.
Feather Radius Feathers the Blur effect applied to pixels that fall between
the Minimum and Maximum channel values. When using map mask as a
Pixel Selection, the Blur effect can create a hard edge on the effect. Use the
