Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

An ambiguous abbreviation that should be avoided. Some writers use it to mean lateral (transverse) chromatic aberration, TCA, while others use it to mean longitudinal (axial) chromatic aberration, LoCA. LCD: Liquid crystal display. A technology often used in the monitor screens of digital cameras, etc. [4] [11] LED: Light-emitting diode ...
The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly.
In photography, stopping down refers to increasing the numerical f-stop number (for example, going from f / 2 to f / 4), which decreases the size (diameter) of the aperture of a lens, resulting in reducing the amount of light entering the iris of a lens. [1] [2]: 112 Reducing the aperture size increases the depth of field of the image.
The history of the single-lens reflex camera (SLR) begins with the use of a reflex mirror in a camera obscura described in 1676, but it took a long time for the design to succeed for photographic cameras. The first patent was granted in 1861, and the first cameras were produced in 1884, but while elegantly simple in concept, they were very ...
An isobar (from Ancient Greek βάρος (baros) 'weight') is a line of equal or constant pressure on a graph, plot, or map; an isopleth or contour line of pressure. More accurately, isobars are lines drawn on a map joining places of equal average atmospheric pressure reduced to sea level for a specified period of time.
Ilford sold a number of cameras under its own name but made for it by other manufacturers, starting with a box camera in 1902, but most were made in the 1940s and 50s. The Ilford Witness was a rangefinder camera with interchangeable lenses announced in 1947, but not released until 1953 because of manufacturing difficulties; there is an example ...
One is to use two cameras separated by the required distance, the other is to shift a single camera the required distance between shots. The shift method has been used with cameras such as the Stereo Realist to take hypers, either by taking two pairs and selecting the best frames, or by alternately capping each lens and recocking the shutter ...
