May I ask the great gods what it means to focus on infinity and hyperfocal distance in photography?

Focusing on infinity means setting the camera focus to infinity (refer to the focus scale, when it indicates infinity, it means focusing on infinity). Specific operations, generally manual focusing, can also focus on distant Gao Fancha targets automatically.

Hyperfocal distance, due to the deep background of the lens, is generally called the distance that can be clearly imaged after focusing is hyperfocal distance. Focusing the camera on a certain point in the distance and controlling the aperture to make the other end of the depth of field infinite, then the shortest photographing distance from infinity to the depth of field is the hyperfocal distance distance.
