How to tell whether a photographer uses a telephoto lens or a wide-angle lens in a movie picture?

Wide angle, short focal length, generally 24-38 mm.

Super wide angle, shorter focal length, focal length range13-24 mm.

A telephoto lens with a long focal length, exceeding 200 mm.

The focal length of the human eye is 35-55mm, and the viewing angle is about 120 degrees. However, due to the relationship between concentration and retina, the clear visual angle of human beings is only about 60 degrees.

Wide-angle lens, because of its short focal length, has a larger viewing angle, generally 60-90 degrees, which means that wide-angle lens can shoot more scenes in a very close place, but the viewing angle is larger, resulting in a greater depth of field effect.

If there is a fisheye eyepiece, that is, the lens is spherical, it will shoot a wider range of scenery, even close to 180 degrees.

A telephoto lens with small viewing angle, weak perspective and short depth of field. It feels like a figure standing in front of a painting, and there is little difference in figure size between the foreground and the background, because the perspective is weak, while the perspective of wide-angle and short-focus lenses is large, and the difference in figure size between the foreground and the background is obvious.

Usually take a picture of a person standing under the moon, and the huge moon behind him is a telephoto lens. . . .

A telephoto lens gives a sense of stability.
