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 ...
Additive system of photographic exposure. A system to aid calculation of correct exposures, developed in the 1960s. Some aspects are included in Exif. [5] APS-C: A film format defined by the Advanced Photo System as 25.1 × 16.7 mm. Different manufacturers use this term for image sensors measuring between about 20.7 × 13.8 mm to 28.7 × 19.1 ...
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 ().

The term "forward-looking" is used to distinguish fixed forward-looking thermal imaging systems from sideways-tracking infrared systems, also known as "push broom" imagers, and other thermal imaging systems such as gimbal-mounted imaging systems, handheld imaging systems, and the like. Pushbroom systems typically have been used on aircraft and ...
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
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 second gimbal, inner gimbal, is mounted in the gyroscope frame (outer gimbal) so as to pivot about an axis in its own plane that is always perpendicular to the pivotal axis of the gyroscope frame (outer gimbal). This inner gimbal has two degrees of rotational freedom. The axle of the spinning wheel (the rotor) defines the spin 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".
