Creating Smooth Edges in Photoshop

- Learn how to smooth edges of a shape in Photoshop.
- Step 1
	First, create a new image, 200x200 pixels and fill the background with white. Create a new layer [Shft+Ctrl+N]. Then, use the Rectangular/Elliptical Marquee Tools [M] to create any shape you want.
- Step 2
	Now we need to select our shape. Do it by holding Ctrl and clicking on this layer with the left button of your mouse. The next step is to add layer mask to our shape. Click on button, this will add layer mask. Then, deselect the layer [Ctrl+D].
- Step 3
	On the top toolbar, go to Filter| Blur | Gaussian Blur... The window with options will open, select the value of the Radius that will make your shape smooth. I used 4.0. To make our job easier, we need to make our layer mask visible. Do it by holding Alt and clicking on the layer mask with the left button of your mouse.
- Step 4
	Now, we need to adjust levels of our image. To do it go to Image | Adjust | Levels... The window with options will open and you will see 3 triangles. Use your mouse to drag all of them to the center and you will notice that your shape will start to look smooth. Play around with different triangle positions to get the result you want.

	Now is the time to apply layer mask to our shape. Right click on the layer mask and select "Apply layer mask". Congratulations, you now know how to smooth edges of a shape in Photoshop.
