What is feathering?
Feathering is a way to soften the hard edges of an object in your image. By gradually fading between the colors of the pixels on the edge and the pixels surrounding it, feathering can help you make a newly added element blend in with the rest of your image. But that’s not the only reason you might want to feather an edge.

Feathering isn’t the only way to soften up an edge. Photoshop offers other options with their own distinct benefits.
