'''2D copying''' refers to making a two-dimensional facsimile of a two-dimensional object.

<!--T:14-->
Examples of this include:

<!--T:15-->
* using a digital scanner
* taking a screenshot of a computer program, computer game, TV program or film

<!--T:16-->
* photographing books, etc. with the intention of faithfully reproducing the 2D content

<!--T:17-->
* photographing 2D art (e.g. paintings)
* using a photocopier
* line tracing

<!--T:18-->
2D copying does not generate any new copyright because the resulting work is defined entirely by the original work; there is no creative input. Therefore, authors who create 2D copies are not entitled to copyright for these works, and the copyright of the original work applies.

<!--T:19-->
For Commons, this means 2D copies are only free if the original is also free. A book or photograph whose copyright has expired is free, as are computer programs ''if and only if'' the program is licensed under open source licenses such as the GPL.

A link should also be provided to the copyright notice of the program so that its license is verifiable.
