A swivel lens is a lens that freely rotates while attached to a camera body. They are used on some compact digital and video cameras . These lenses make it easy for a photographer to aim a camera without moving around too much. Swivel lenses come in different sizes and shapes.
An in-camera effect is any visual effect in a film or video that is created solely by using techniques in and on the camera and/or its parts. The in-camera effect is defined by the fact that the effect exists on the original camera negative or video recording before it is sent to a lab or modified.
3-D audio (processing) is the spatial domain convolution of sound waves using head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space.
Digital cameras provide a certain number of samples per degree or per radian, or samples per mm in the focal plane of the camera. Audio signals are sampled with an analog-to-digital converter, which produces a constant number of samples per second. Some of the most dramatic and subtle examples of aliasing occur when the signal being sampled ...

The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
Rolling shutter describes the process of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, vertically, horizontally or rotationally. Thus, not all parts of ...
The effect is especially noticeable the closer the camera is to the subject, as its amount increases the shorter the focal length is at the same field size. One notable director that frequently employs rectilinear ultra wide angle lenses in order to achieve a distinctive signature style defined by extreme perspective distortion is Terry Gilliam.
