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 ().

Lower-end camera phones use only digital zoom and do not have optical zoom, while many higher-end phones have additional rear cameras, including fixed telephoto lenses that allow for the simulation of optical zoom. Full-sized cameras generally have an optical zoom lens, but some apply digital zoom automatically once the longest optical focal ...
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens . A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1]
A whip zoom (also referred to as a snap zoom or crash zoom) is a type of camera shot in which the camera zooms in or out quickly, [1] [2] allowing the viewer to focus on the subject. [3] Another use of the whip zoom is to enable the shot to be edited as a cut from a long shot to a close up, or vice versa.
Hyperfixation, on the other hand, stems from an inability to turn your attention away from something in a way that's so intense that it might actually impair your life, Adler says. By definition ...
The ISO setting on a digital camera is the first (and sometimes only) user adjustable gain setting in the signal processing chain. It determines the amount of gain applied to the voltage output from the image sensor and has a direct effect on read noise. All signal processing units within a digital camera system have a noise floor.
A sound blimp is a housing attached to a camera which reduces sounds, such as shutter click on SLR cameras, and motors on motion picture cameras. It is primarily used in film still photography, so as not to interfere with the shooting of principal photography [dubious – discuss], and also in other situations where sound is distracting: theatrical photography, surveillance, and wildlife ...
Troxler's fading has been attributed to the adaptation of neurons vital for perceiving stimuli in the visual system. [2] It is part of the general principle in sensory systems that unvarying stimuli soon disappear from our awareness.
