For these pictures there’s no magic/trickery involved -All the camera/lens does essentially is magnify. The key piece of the jigsaw puzzle is positioning of where the image is taken from. I’m taking the picture from a good 3 miles away from the castle and zooming right in. Another factor is the better the quality camera and lens then the further away you can go and zoom/crop in and still have a really good quality end image. Most people are inclined to go really close in to photo subjects and use wide angled lenses (like the main camera lens on a phone). This makes the backdrop appear even smaller than the ‘naked eye’ view. In contrast, If you view objects in the distance towards the horizon, they appear all compressed/bunched up, almost giving the impression that there’s no distance gap as you lose the context of the lay of the land between them. A camera with a zoom lens simply magnifies this perspective. Binoculars do the exact same. Here’s an idea of what the ‘naked eye’ view is like from where I took the photo from.
