A SnorriCam (also chestcam, body mount/bodymount, or bodycam) [1] is a camera device used in filmmaking that is rigged to the body of the actor, [2] with the camera facing the actor directly so that they appear in a fixed position in the center of the frame.
A lens accessory that fits between the lens and camera body and extends the focal length of the lens, often by 1.4x or 2x, at the cost of reduced light, decreased image quality, and slower autofocus. TCA: Transverse (lateral) chromatic aberration or lateral colour. Colour fringes that worsen the further the image point is from the optical axis ...
Features include [28] smart adjustments, advanced color, styles and presets, high dynamic range, skin tone editing, before and after, film grain, healing and cloning tool, dehaze, layers, keystone correction, black and white conversion, ability to print directly from Capture One, and extension to iPad and iPhone with Capture Pilot, [29] noise ...
"Pulling focus" refers to the act of changing the camera lens's focus distance to a moving subject's distance from the focal plane, or the changing distance between a stationary object and a moving camera. For example, if an actor moves from 8 metres (26 ft) to 3 metres (9.8 ft) away from the focal plane, the focus puller changes the lens's ...
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 ().

In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
Body cameras have a range of uses and designs, of which the best-known use is as a police body camera. Other uses include action cameras for social and recreational (including cycling ), within the world of commerce , in healthcare and medical use, in military use, journalism , citizen sousveillance , and covert surveillance .
Astigmatism causes difficulties in seeing fine detail. Astigmatism can be often corrected by glasses with a lens that has different radii of curvature in different planes (a cylindrical lens), contact lenses, or refractive surgery. [5] Astigmatism is quite common. Studies have shown that about one in three people suffers from it.
