No, I’m not advocating murder.  Adolf has gotten into an intimate family photo, and you don’t want him there.  Checking the web persuades you that it takes just a few clicks if you just apply the right software.  Although the basic procedure is well defined, the difficulty of the process varies widely.   There are three steps.  First, you select the area to be eliminated.  Second, you clear the selected area.  Finally, you fill in  or clone the blank area from the remaining parts of the photo.

Sounds simple, doesn’t it?  It is easy if Adolf’s figure is well-defined and contrasting to its surroundings.  But what if Adolf has blowing hair or is standing in a white shirt against a white wall?  Then the selection process requires serious labor and software that permits individual selection adjustments.  If your first step is successful, another click and Cousin Adolf is gone.  Good riddance!   But our travails are not over.  There remains a big hole where Cousin Adolf used to be.  Unless you fill it with some convincing material, your photo will show the obvious: you have taken out someone.  If everyone is standing with their backs to a stucco wall, you simply move a piece of this wall into the blank portion of the photo by the process called cloning.  If Cousin Adolf was standing in front of (say) a painting or partially in front of another person, this process ranges from difficult to impossible.  I have added “before and after” photos where an urn appears on the head of the original shot.  That one required a plausible extension of the background, so it was relatively easy.

I have been surprised by a similar question; people want to recover an object in the back of something else in the photo.  In one instance, an individual even asked for a Photoshop procedure to remove the clothes from a person!.  Of course, we can do what they asked, but it takes whiffeldust and ground unicorn horn for the procedure, both of which are currently in short supply (no doubt due to supply chain problems). For someone asking that kind of question, there is no use in pointing out the logical impossibility of creating new information out of nowhere
