It is photoshopped. I do this stuff all the time.
One area you can tell is on gramps shoulder next to 0’s shoulder is not as dark in the before pic. Also the area where the wall shows through should be showing gramps arm and not the wall. The area just to the right of gramps knee has a blue tinge which is gone in the shopped pic.
Probably other areas but those sure jumped.
Also they put gramps hand over 0’s shoulder.
Why isn’t it over granny’s shoulder also? Hmmm?
