The hyperfocal point is the closest point to the camera that appears acceptably sharp when a lens is focused at infinity. Focusing on this point ensures that the depth of field extends from a distance halfway between the hyperfocal point and the camera all the way to infinity, making it a key concept in landscape and architectural photography.
Using the hyperfocal point effectively allows photographers to maximise sharpness throughout the scene, capturing both foreground and background details with clarity. Understanding and applying this technique is essential for achieving images with extensive depth of field, especially when working with wide-angle lenses and smaller apertures.
