On the compression background of telephoto lens
The so-called telephoto lens compression background is actually a perspective problem. According to the perspective principle, it is found that the scenery is near big and far small, such as patting the telephone pole on the roadside. The length of the nearby telephone pole occupies the height of the whole picture, and the telephone poles at the back are smaller in turn, and only sesame seeds are big in the distance. This picture gives a sense of distance. Especially shooting with a wide-angle lens can better reflect this sense of perspective.
When a telephoto lens shoots a distant scene, if there is no reference object with a familiar length, two buildings with a distance of 300 meters and a distance of 500 meters behind them seem to be next to each other, which is the phenomenon of distance compression. If the contrast has not changed, it is difficult for you to estimate the distance between the front building and the back building in the picture below.
