Now, just for the sake of demonstration, I've gone ahead and apply the Feather value of 42 pixels because Feather like Radius is measured in pixels and also is measured as a Radius value. In the case of Feather, we are blurring the selection outward 42 pixels and inward 42 pixels as well, and that blur is evenly distributed so we get essentially a fuzzy selection outline.

That's not even sort of what I want; I want a nice crisp clean selection outline. So I'll reduce that Feather value to 0 pixels. But what happens if we increase the Radius value to that exact same 42 pixels and press the Tab key. Well, we might look at the results and think that this is some sort of smart blurring that is going on that the Refine Mask command is looking at these details. It's going ahead and applying ...
