HYPERFOCAL DISTANCE Meaning and
Definition
-
Hyperfocal distance refers to a fundamental concept in photography and optics that relates to achieving the maximum depth of field (DOF) in a photograph. It is defined as the closest distance from the camera lens at which objects will be in sharp focus when the lens is focused at infinity. In other words, it is the distance that allows objects to be acceptably sharp from half the hyperfocal distance away to infinity.
The hyperfocal distance is especially useful when shooting landscapes or scenes where an expansive DOF is desired, as it ensures that objects at different distances are sharp and in focus. To determine the hyperfocal distance, factors such as the focal length of the lens, the aperture size, and the circle of confusion (a measure of acceptable sharpness) are taken into account.
Knowing the hyperfocal distance enables photographers to set the focus point on their lens in a way that covers as much of the scene as possible while maintaining sharpness throughout. By focusing at the hyperfocal distance, one can achieve a greater DOF, resulting in a clearer and more detailed photograph.
Photographers often refer to hyperfocal charts or smartphone apps to determine the appropriate hyperfocal distance based on their chosen focal length and aperture settings. It is an essential concept to grasp for those looking to capture landscape photography or scenes where a wide DOF is paramount.

Etymology of HYPERFOCAL DISTANCE
The word "hyperfocal" comes from two root words: "hyper" and "focal".
The term "hyper" originates from the Greek word "huper", meaning "over" or "beyond". In modern usage, "hyper" is often used to denote something excessive or beyond the norm.
The word "focal" is derived from the Latin word "focus", which means "hearth" or "fireplace". In optics and photography, "focus" refers to the point at which light rays converge to form a clear image.
When combined, "hyperfocal" refers to a point in a scene that is beyond the closest object in focus, where the depth of field extends to infinity. It is an important concept in photography, especially in landscape or architectural photography, where maximizing the depth of field is often desired to achieve sharpness throughout the scene.
