The rule of thirds is a rule of thumb for composing visual art such as designs, films, paintings, and photographs. [3] The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines, and that important compositional elements should be placed ...

The rule of thirds is a rule of thumb used when planning for the deployment and usage of a military organization.According to this principle, one third of the total military forces involved should be available for operations, one third should be preparing for operations, and the final third, having been on operations, should be recuperating.
A grid applied within an image (instead of a page) using additional angular lines to guide proportions. In graphic design, a grid is a structure (usually two-dimensional) made up of a series of intersecting straight (vertical, horizontal, and angular) or curved lines (grid lines) used to structure content.
Personally, I think it sad that this fundamental concept (the rule of thirds) that worked so well with 135 film was overlooked by digital camera makers when they adopted the 4:3 ratio. Of course you can still compose using the rule in 4:3, but there was a mathematical simplicity to it with 135 that this article made me think about.
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 .
