Feathered (Soft/Smooth/Gradual) Selections
While regular default area selections have a sharp outline, many times we need to select areas where the selection is blend smoothly/gradually with the rest of the image (also called as "soft selection")
The Feather's value defines how the edges of the object/selected area will look. The lower the value of the Feather is, the sharper will the edges of the object/selected area be.
The higher the value of the Feather is, the smoother and "soften" will the edges of the object/selected area be (will cause the edges to gradually integrate with the background).
When the Feather's value is greater than 0 (i.e. when there is Feather), it is possible to select one of two types of Feather: Smooth feather edges or Sharp feather edges. The selection of the Feather type is done with the radio dial or the Sharp button (depending on which tool you are using), located near the Feather Box.
