Macro stereo
These are extremely close-up images which have been photographed with a reduced stereo base so that a correct stereo recession will be maintained.

Macro stereo photography
This is stereo photography with which the films image is around a similar or increased size of the images original size.

Magic Eye
This term relates to computer generated optical illusions that if ‘freeviewed’ will show numerous hidden images of objects and shapes.

Mirror stereoscope
A mirrored stereoscope is a stereo viewer that incorporates numerous angled mirrors, similar to the Wheatstone and Cazes stereoscopes.

This refers to a condition with which one homologue is at a different height to the other. When the misalignment is rotational on both views, there is a ‘tilt’, however if it is in just one view only then there is a ‘twist’. Diplopia and eye strain are results from viewing a misaligned stereogram.

Monocular areas
These areas are parts of a scene in a stereo image that appear in one view but not in another.  They can appear to be natural if they are situated behind the stereo window, or if they are in front they will appear unnatural, just like in the case of floating edges .

Monocular cues
Please see ‘Extrastereoscopic Cues’.

A mount when referred to in stereo usage is a specialist holder or card that is used to locate, secure and protect the two images within a stereo pair. The term usually includes any mask or framing device that may be incorporated.

Mounting is the process of attaching the left and right views to a mount or mask so that they both are correct horizontally (so the stereo view will be held in the correct place to the stereo window) and vertically (to avoid misalignment).

Mounting jig
The mounting jig is a device used to help the mounting of stereo pairs in a correct register. It usually incorporates an alignment grid which is situated below the mount holder, and a set of viewing lenses which are above the film chips in order to enable each eye to concentrate and focus on the correct image and fuse the images.

MPEG stands for ‘Moving Picture Experts Group’. Mpegs are a type of video/audio file that can be found online. They come in three different MPEG standards which are: MPEG-1, MPEG-2, and MPEG-4.

This is the process of taking both the left and right image and then fusing them with a multiplexing software tool or alternatively with a multiplexer to create on 3D stereo image.

This is the process of fusing the two images needed for a stereoscopic display within a bandwidth.
