Content Aware Fill is one of those features of Photoshop that many users love to hate. So much so that quite a few of us have called it Content Aware Fail since it was first introduced in CS5. Personally, I’ve only found it to be really all that useful for extending clear blue skies, and even there it occasionally wants to put a branch or a building flying in the middle of nowhere.
This video from the Jesús Ramirez Photoshop Training Channel, though, shows me something I never knew about Content Aware Fill. That it respects layer masks. Something which turns it into a much more reliable and useful tool. This method makes it very easy to use Content Aware Fill where you previously might not have even tried.
