Dude, you might want to check the part where it says "when talking about images with the same field size".
We all understand that it is perspective but when using actual photographic lenses in real world applications, the distortion effects are clearly observable. Its not really possible to crop a 16mm to a 300mm fov in the real world, nor can you make the 300mm replicate the perspective of the 16mm when shot close up. That's why real people talk about "compression" when discussing long lenses and portraiture or landscape. We know that the lens isn't literally casting a magic spell to literally warp the fabric of spacetime and literally crush a model's face flat. Compression is a photographic term to describe a photographic effect and everybody knows what you mean when you say it.
Why, it is so badly written as to cause half this confusion.
As for "We all understand that it is perspective"
well, that isn't true, many don't, and because of that we constantly hear this "lens compression" meme.
No, "compression" is an uneducated term to describe what photographers see when they mean perspective, "compression" isn't a "photographic effect"
it is what is seen from the viewpoint you have.
If you want the background to appear larger in relation to the subject make the distance between you and them similar, if you want the background to be smaller in relation to the subject make the distance between you and the subject smaller than the distance from the subject to the background, this has nothing to do with the lens. The "effect" is perspective, another, inaccurate, term for it really isn't needed.
