Định Nghĩa và Ý Nghĩa của "hyperfocal distance"

What is "hyperfocal distance"?

Hyperfocal distance is the closest distance at which a camera should be focused to ensure that everything from that point forward, up to the farthest point the camera can see, appears sharp and in focus. By setting the lens to this distance, both objects that are close to the camera and those far away will be clearly visible in the photograph. This technique is often used in landscape photography to make sure the entire scene, from the foreground to the background, is sharp.
