S or Tv: Shutter priority or Time value enables manual control of the shutter speed, and aperture is calculated by the camera for proper exposure (given an ISO sensitivity). M: Manual mode both shutter speed and aperture are independently set manually (with ISO sensitivity also set manually), where proper image exposure requires accurate manual ...
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 camera projection matrix is derived from the intrinsic and extrinsic parameters of the camera, and is often represented by the series of transformations; e.g., a matrix of camera intrinsic parameters, a 3 × 3 rotation matrix, and a translation vector. The camera projection matrix can be used to associate points in a camera's image space ...
The user guide engraved into a model of the Antikythera Mechanism. User guides have been found with ancient devices. One example is the Antikythera Mechanism, [1] a 2,000 year old Greek analogue computer that was found off the coast of the Greek island Antikythera in the year 1900.
