Shading the selection in Adobe PhotoShop

Whether you’ve made a selection by Photoshop tools or used a plug-in you’d want  your selection to look nice and smooth on a new background. If the edges of the selected image were not softened or feathered during the process of selection you may shade them in Photoshop.

To do that open Select menu and choose Feather

In the opening dialog window type in a number of pixels to be feathered (2-5 are usually enough)

Now you can copy your selection, paste it into a new environment and evaluate the result

No shading	5 px shading
15 px shading	50 px shading
