So we now have the marching ants selection around the sky with a 3 pixel feather.
这样我们有了包围天空的“蚂蚁行军”选区，并且已经羽化了3个像素。

In this case I want to put a small feather on the selection before we mask as even though I want a crisp line, it's very rare that you don't need at least a small amount of feathering.
在这个例子中，虽然我很希望边缘清晰，但是我要使选区有一点羽化。一点都不羽化的情况很少见。

After you have closed the path, right-click on the workspace and choose "make selection" (feather 0).
