Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...
Also may mean "Perspective Control" for a lens that has the ability to shift to tilt to control linear perspective in an image. May also stand for personal computer in conjunction with digital photography. PDAF: Phase-detection autofocus. One of the mechanisms of automatic lens focusing. PF: Purple fringing. A form of chromatic aberration in ...
The term originally referred to the physical cutting of a film strip and the subsequent splicing together of non-adjacent frames, but is now also used to refer to a similar process in computer editing software. It is often used interchangeably with the term edit, though edit may also imply any number of transitions or effects. cut in cut out
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 ().

Filming with a handheld camera stabilizer An operator uses a camera stabilizer in a low-angle shot. A camera stabilizer, or camera-stabilizing mount, is a device designed to hold a camera in a manner that prevents or compensates for unwanted camera movement, such as "camera shake".
With popular photo apps like Instagram, Snapchat and Flickr, it's pretty safe to say that most of us are tapping into some seriously ambitious photography skills. Because of apps such as these ...
The word "photography" was created from the Greek roots φωτός (phōtós), genitive of φῶς (phōs), "light" [2] and γραφή (graphé) "representation by means of lines" or "drawing", [3] together meaning "drawing with light". [4] Several people may have coined the same new term from these roots independently.
Other head types include the gimbal, fluid, gear, alt-azimuth, and equatorial heads. Fluid heads and gear heads move very smoothly, avoiding the jerkiness caused by the stick-slip effect found in other types of tripod heads. Gimbal heads are single-axis heads used in order to allow a balanced movement for camera and lenses. This proves useful ...
