Can the camera capture people one meter away from the bus stop?

Take photos with a camera one meter away from the bus stop, because this is a public place, and there are many people, so you should be able to photograph people. The number and size of people being photographed depend on the focal length of the lens used by the camera, how many people are in the range of the lens angle of view when shooting, and how far away these people are from the camera.

The practical significance of explaining this problem lies in understanding the influence of lenses with different focal lengths on the number and size of people (or things) photographed because of different viewing angles and different shooting distances. In order to choose the appropriate lens focal length and shooting distance according to the shooting needs in photography.

1. The shorter the focal length of the lens, the larger the viewing angle and the wider the shooting range. Therefore, in a fixed place, shooting at the same number of people coming and going, the shorter the focal length of the lens used, the more people can be photographed.

2. lenses with different focal lengths shoot a person at the same distance. The shorter the focal length, the smaller the person photographed on the screen. Take the distance of 1 m for example. The person whose focal length is 16mm (for simplicity of description, the focal length has been converted to full width) is the whole body, and the person whose focal length is 50mm is the upper body. If you use a focal length of 85mm, it will be as big as a close-up of your face. Therefore, at a very close distance from the bus stop 1 m, we should use a focal length below 16mm to shoot the portrait of the whole body.

3. When the focal length of the lens has been determined, the farther a person is from the camera, the smaller the person being photographed is on the screen. For example, with a focal length of 50mm, you can take a close-up of the face at a distance of 0.5 meters, a close-up of the upper body at a distance of 1 meter, and a close-up of the whole body at a distance of 2.6 meters. That is, people with a focal length of 50mm and a distance of less than 2.6 meters can't take pictures of the whole body.

4. lenses with different focal lengths should make people have the same figure. The shorter the focal length, the closer the shooting distance. For example, to take a full-length photo, the focal length should be 16mm, the subject should be at 1 m and 2.6 m with a focal length of 50mm and a focal length of 200mm, and the person should be at a distance from the camera 10 m.
