How create rounded corners for a layer or selection in Photoshop
I have a white screen area 142x113 px in Photoshop.
I select half of this area and tried
Smooth but it does not work the way I expected. I tried decreasing the selection's width and now the
Smooth command works, but not very well.
I have 3 questions:
- Why smooth does not work in the first condition?
- What are the best ways for creating smooth edges (rounded corners) of a selection?
- What are the best ways for creating smooth edges (rounded corners) of a Layer?
I don't know why Photoshop has never had a "rounded rectangle" selection tool. Seems like it ought to, doesn't it? But it doesn't. So, to answer your questions:
"Smooth" is designed to even out rough edges. It doesn't do effective job of rounding corners because that's not what it's for.
To create a selection with rounded corners, you have to start with a path and turn it into a selection: Use the rounded rectangle Shape tool in "Path" mode (it's the middle icon, the one with the pen, between the Shape Layer and Fill Pixels icons) to create a path with the rounding you want, then press Ctl - Enter (Windows) or Cmd - Return (Mac OS) to turn the path into a selection.
To mask a layer, just move the selection to where you want it then click the Layer Mask icon at the bottom of the Layers panel. That will create a layer mask based on your selection.
If you use the rectangle tool to make your selection then modify> smooth> change pixel size to round edges.
