If you’re cutting and pasting a selection from one layer onto another layer in Photoshop, you may find that sometimes there is a white or light coloured line of pixels around some of the objects – a sort of halo effect. It’s particularly obvious when you place the object over a dark coloured background.
In the image below, the bird was selected from a light coloured background and pasted onto a dark blue gradient. The white edge can be seen particularly around his beak and the dark feathers on his head and back. So how do you get rid of this?
To get rid of this edge or fringe, you can use Photoshop’s “Defringe” command.
1. Make sure you have the correct layer selected
2. Choose Layer > Matting > Defringe. For starters, try a setting of 1 pixel and click OK.
At this point Photoshop goes off and replaces the white edge pixels with a mixture of the colours in the background and the colours in your object. If 1 pixel doesn’t do the trick, then try Defringe again with either 2 or 3 pixels.
