Video magnifiers are electronic devices that use a camera and a display screen to perform digital magnification of printed materials. The display screen is usually LCD or a similar flat-screen technology (although older video magnifiers have used CRT displays), and the device usually includes a lamp to illuminate the source material.
An incandescent lamp...is placed below the film...and the light passes up through the film, shutter opening, and magnifying lens...to the eye of the observer placed at the opening in the top of the case." [33] Robinson, on the other hand, says the shutter—which he agrees has only a single slit—is positioned lower, "between the lamp and film ...

The multiplane also made possible new and versatile types of in-camera special effects for animated films using, for example, 3D practical elements/mock-ups in foreground, filters and planar lighting, distortion glass and reflections, to achieve naturalistic moving water, flickering light and other subtle effects.

Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography ( Relièphographie ) for 3D autostereograms .

Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
