Knowing how to edit a head swap in Photoshop is an imperative skill to have as a photographer. I don’t necessarily use it all the time, but it IS needed if you have a great photo of everyone looking and smiling at the camera for grandma, except one person is blinking. I also do head swaps for more minor effects, as shown in this example here.
Enjoy and let me know if you have any questions!
