No, you are completely wrong. I don't duplicate layer with the over-the-shoulder shot and then I start to deleting parts of orange shoulder. I did this differently.
Please, read carefully what I wrote and shown on screens. When I finished corner pinning I start to deleting A PART OF CORNER PIN IMAGE. Not duplicated layer of my shoulder shot like you talked. So I still didn't get answer of my question why we can't use a MASK on obcject modified by CORNER PIN?
See agan on that screen and look what happened. A corner pinned image is deleted by mask but mask even doesn't touch this image!
Image may be NSFW.
Clik here to view.
I wonder why...
