Using a filter effects mask
When you apply a i lter to a layer that has been converted for Smart Filters, a mask, called
the Filter ef ects mask thumbnail, is created. This provides the ability to selectively modify
a i lter ef ect. The thumbnail appears on the smart object layer as a white box labeled
Smart Filters. You can click on the mask to activate it, and then paint with shades of black
or white to hide or show the i lter's ef ect on the layer. You'll now convert a layer for
Smart Filters, apply a few i lters, reduce the opacity of those i lter ef ects, and then mask
the ef ects to appear on only portions of the image.
