hyperfocal distance造句

Some cameras have their hyperfocal distance marked on the focus dial.
This makes a bigger circle of confusion and smaller hyperfocal distance.
The hyperfocal distance is the closest distance at which a objects at infinity acceptably sharp.
The hyperfocal distance is entirely dependent upon what level of sharpness is considered to be acceptable.
You're conveniently forgetting about half of the plane " not " beyond the hyperfocal distance.
It's difficult to find hyperfocal distance in a sentence. 用hyperfocal distance造句挺难的

Focusing on the hyperfocal distance is a special case of zone focusing in which the far limit of DOF is at infinity.
Thomas Sutton and George Dawson define " focal range " for what we now call " hyperfocal distance ":
When the subject is at the hyperfocal distance or beyond, the far DOF is infinite, and the near : far ratio is zero.
When the subject distance s is small in comparison with the hyperfocal distance, the second term in the denominator can be neglected, leading to
When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance out to infinity will be acceptably sharp.
Most models have a fixed focus lens, set to the hyperfocal distance of the maximum aperture of the lens, often at around 10 meters ( 30 ft ).
If the camera lens is focused at or beyond its hyperfocal distance, then the depth of field becomes large, covering everything from half the hyperfocal distance to infinity.
If the camera lens is focused at or beyond its hyperfocal distance, then the depth of field becomes large, covering everything from half the hyperfocal distance to infinity.
As the hyperfocal distance is the focus distance giving the maximum depth of field, it is the most desirable distance to set the focus of a fixed-focus camera.
Using p for hyperfocal distance, D for aperture diameter, d for the diameter that a circle of confusion shall not exceed, and f for focal length, he derives:
