Do not fill this in!==A to Z== * [[light meter|actinometer]] - a [[light meter]] that works by [[actinometry]]. * [[actinometry]] - measuring light by the speed of a photo-chemical reaction. * [[adapter]] * air release - a remote control [[shutter release]] similar to a [[cable release]], worked by air pressure - usually consisting of a piston attached to the shutter, with a rubber tube leading off to a rubber bulb which is squeezed to fire the shutter. * [[Anastigmat]] - marketing term for anastigmatic corrected [[lens]]es * [[lens#Aperture|aperture]] - An opening in a lens that controls the amount of light passing through it. * [[aperture priority]] - A metering method that recommends a shutter speed based on a desired aperture. * [[aspect ratio]] - the relative sizes of height and width to each other; e.g. of film, sensor, computer monitor / [[LCD]] or prints * [[lens#Aspherical|aspherical]] * [[camera#Autoexposure|auto exposure]] - An in-camera exposure system that attempts to set the aperture and shutter speed (and [[CCD]] [[Film Speed#Speed_in_Digital_Cameras|sensitivity]] in many digital cameras) to get the best exposure for the current lighting situation. * [[autofocus]] - The ability of any camera/lens to focus itself electronically to the appropriate image subject distance. * [[autographic]] - a feature allowing hand-written comments on the negative. 1914-1934 * [[auxiliary lens]] - a lens that attaches to the front of another lens to change the field of view (narrower, wider) or focusing characteristics (able to focus more closely). * [[Camera#Back|back]] - The back of a camera, containing the recording media. * [[Bakelite]] - an early form of plastic, used in camera making from the 1930s to the 1960s. * [[tripod#Ball Head|ball head]] - tripod head based around a lockable, free-moving ball. * [[lighting#Barn Doors|barn doors]] * [[lens#Barrel|barrel]] * [[Bay I]] - Bayonet type I. A type of filter mount commonly used on [[TLR]]s. * [[Bay II]] - Bayonet type II. A type of filter mount used on some [[TLR]]s. * [[bellows]] * body cap - a cap to close the lens mount, and keep dust out of the camera when the lens is removed from the body. * [[bokeh]] is how a [[lens]] draws unsharp/out-of-focus image areas * [[lighting|bounce flash]] - reflecting a flash from a wall or ceiling (or perhaps a special flash diffusing reflector, such as a [[lighting#Umbrella|brolly]]) to soften the harsh shadows and contrast produced by direct flash. * [[box camera]] - a class of camera types, commonly shaped as cuboid boxes. * [[bulb mode]] ("B") - a setting which allows a camera's shutter to be opened and closed manually for the intended purpose of flash photography. * [[exposure|bracket]] (exposure/white balance) * [[bridge camera]] - originally a [[SLR]] with a fixed zoom lens, nowadays a medium-size digital wide-range zoom camera with electronic viewfinder (EVF), intermediate between the [[compact camera]] and [[SLR]] * [[brilliant finder]] - a very small, simple [[viewfinder|finder]] designed to be looked down into * [[lighting#Umbrella|brolly]] - Another name for an [[lighting#Umbrella|umbrella]]. * [[camera]] * [[camera shake]] - a blurring of a photo due to the camera moving - usually unintentionally. * [[camera system]] * [[cable release]] - An attachment that screws into a shutter release that allows you to trip the shutter mechanically while not otherwise touching the camera. * [[CCD]] - Charge-Coupled Device - a component that can be used as the light sensor in analog-electronic or [[digital camera | digital]] cameras. * [[CdS]] - Cadmium Sulphide - a type of [[light meter]] cell. * [[center-weighted]] - an in-camera [[light meter|light-meter]] system that favors the center of the frame although it does take into account the rest of the frame to a lesser extent. * [[click stops]] - See also [[detents]]. * [[Clones, Rebadges and Rebrands|clone]] - equipment made, under license from original manufacturer, by another manufacturer. * [[Coated#Coating_against_reflections_between_lens_groups|coated]] - See [[Coated#Coating_against_reflections_between_lens_groups|lens coating]]. * color balance * color-blind - the most basic black and white photographic emulsion, sensitive to violet and blue light only. * [[colour temperature]] * [[compact camera]] * [[Compur]] - a brand of camera shutters, made by the F. Deckel company of Munich, Germany. * contact print - a print of a negative made by laying the film directly on the paper and exposing to light. * [[contrast]] * [[convertible lens]] * [[Copal]] - a brand of Japanese camera shutters. * [[coupled rangefinder]] - A rangefinder which is mechanically coupled to the focus adjustment on a lens. * [[crop]] - to reduce a picture to a smaller area, cutting off the edges - usually to leave a better composition. * [[cross processing]] - developing a film using a process intended for a different kind of film - i.e. using the "wrong" process; done for the special effects this produces, such as wild colour changes. * [[camera#Back|data back]] - a camera back for film cameras that imprints (or burns) information onto a film frame. * [[dark slide]] - a thin box, designed to hold sheet film so that it can loaded into a camera (typically a [[view camera]]) without exposing the film to light. A sliding cover can be opened whilst in the camera to allow the film to be exposed to the lens; sometimes this cover is itself referred to as a dark slide. * [[lens#Depth of field|depth of field]] - The range of distances (from near to far) within which a scene will be considered to be "in focus" (within which the [[circle of confusion]] will be acceptably small) * [[detents]] - Positions on a moving dial (e.g. shutter speed or aperture dial) from which movement needs some friction - "click stops". * [[diaphragm]] - The mechanism in a camera lens that creates a variable [[aperture]]. * [[digital zoom]] - a method of zooming via cropping and upsizing instead of physical lens adjustment * [[diopter]] - An optical adjustment that allows someone to adjust the viewfinder's focus to their vision; also a unit for measuring lens strength. * [[digital camera]] * double exposure - intentional or unintentional action of exposing the same film frame twice. * [[DSLR]] - Digital Single Lens Reflex camera * [[lens#Element|element]] - An individual piece of glass within a lens. * [[E-TTL]] - * EVF - Electronic View Finder: [[LCD]]-preview screen that is just visible through an [[ocular]], used in digital [[bridge camera]]s * [[everset shutter]] - A shutter that is tripped by the sole energy of the finger pressing the release. It does not need cocking but cannot provide high speeds and needs the release pressing harder than a cocking shutter. * [[EXIF]] - a specification for digital image file storage * [[exposure]] - The combination of shutter speed, aperture, [[Film Speed|film sensitivity]], and light used to create a single photograph. <!-- ??? --> * [[exposure compensation]] - increasing or decreasing the exposure to compensate for dark or light subjects which may cause a [[light meter]] to indicate the "wrong" exposure. * [[exposure value]] (EV) * [[lens tube extension|extension tubes]] - tubes used to move the lens further from the [[Lens#Focal_Plane|focal plane]], to allow closer focusing.
