This video in the Fine Art category will show you how to use the refine edge in Photoshop. This video tutorial is from Yanik Photo School. This feature is available in Photoshop CS3. If you are shooting objects in isolated background and you want to cut that object out and put it on a different background, the object will have jagged edges. Refine edge will help in smoothing those jagged edges. First select your object, then go to 'select' and click on 'inverse' and you have selected your object. Now click on 'refine edge' and the dialog box will appear. The video then goes on to demonstrate all the other features.
