In contrast to most other eye glasses, shooting glasses usually only have one lens that corrects the ametropia of the dominant eye, which is used for aiming.This lens is selected in such a way that the maximum visual acuity lies on the font sight line element near the muzzle of the (non-magnifying) open type or diopter and globe type match sight line elements to get three points positioned in ...
An electronic shutter can compensate for the exposure change caused by a speed ramp without changing the aperture and affecting depth of field. Other types of shutter adjustments, such as an out-of-phase shutter and a fluttering shutter, are also possible. Normally the film is held steady in the gate whenever it is exposed to light.
One then reframes the scene and fully depresses the shutter to take the photo. Unlike other modes, this also sets focus and requires two separate metering/focus stages. A-DEP: [3] Canon also offers A-DEP (Automatic DEPth of field) mode on some cameras, which sets the depth of field and focus in a single shot. However, this requires lining up ...
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp. A shutter of ...
Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.

Burst mode, also called continuous shooting mode, sports mode, continuous mode, or burst shot, is a shooting mode in still cameras where several photos are captured in quick succession by either pressing the shutter button or holding it down. [1] This is used mainly when the subject is in successive motion, such as sports photography. The ...
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 ...
