In cinematography, a jib is any boom device used to mount a camera on one end, and a counterweight with camera controls on the other. [1] In principle, it operates like a see-saw, with the balance point located closer to the counterweight, which allows the end of the arm with the camera to move through an extended arc. Typically a jib permits ...
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 ().

Manipulation of a photo to alter a model's appearance can be used to change features such as skin complexion, hair color, body shape, and other features. Many of the alterations to skin involve removing blemishes through the use of features included within popular image editing programs which are designed for just such purposes.
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 ...
For small hand-held cameras, a harness or contoured frame steadies the camera against the photographer's body. In some models, the camera mount is on an arm that protrudes in front of the photographer; beneath the camera is a handle grip. Another variation positions the camera atop a fulcrum brace against the photographer's chest or abdomen.
Some cameras have tens of modes. Many cameras do not document exactly what their many modes do; for full mastery of the camera, one must experiment with them. In general: Action or sports modes increase ISO and use a faster shutter speed to capture the action. Landscape modes use a small aperture to gain depth of field. Flash may be deactivated.
A body camera, bodycam, body-worn video (BWV), body-worn camera, or wearable camera is a wearable audio, video, or photographic recording system. Body cameras have a range of uses and designs, of which the best-known use is as a police body camera .
The camera encodes its rendered image into the JPEG file using one of the standard gamma values such as 2.2, for storage and transmission. The display computer may use a color management engine to convert to a different color space (such as older Macintosh's γ = 1.8 color space) before putting pixel values into its video memory.
