eli5 : How do people photoshop things out of pictures without knowing what the background is?

Question

Do people have to take TWO pictures at the same angle in order to photoshop things out? How do they know what the background looks like?

Answer 1

they make it up using what’s around. if your subject stands in front a green grass field, you just make up more green grass field. but if your subject happened to be standing in front of 1 red rose in a green grass field, then your made up more green grass field would be wrong, as it is missing a red rose. but unless someone knew there was a red rose behind the subject, no one would know the picture is inaccurate.
