Hyperfocal distance

This months gallery ties up to Eugene's article about

Technical aspects of your camera :- Focal length Distance between the optical centre of a lens and its focal point. In practice, the focal length is a measure of magnification and angle of view of a given lens or zoom setting. It is usually measured in millimetres. Focal plane Flat surface where the image is focused in a camera. It is the plane where the film or imaging chip sits. Histogram Graphical displays used as a way of depicting and manipulating the brightness, tonal range, and contrast of a digital image. Hyperfocal distance The shortest distance at which a lens can be focused so that depth of field stretches to infinity for a given aperture and focal length. When focused at the hyper focal length, depth of field stretches from exactly half the hyper focal distance to infinity.
