[edit] Summary

Scene from a Team Fortress 2 promotional trailer, demonstrating new flame and dynamic light/shadow technologies in the Source engine.

[edit] Fair use rationale for Source engine

While this picture is subject to copyright, its use within the article Source engine is believed to qualify as fair use under US copyright law for the following reasons:

1. The image is used to illustrate a graphical capability of a game engine; this concept cannot easily be explained without the use of an image.
2. It is taken from a promotional video that was made public by the copyright holder with the aim, in part, of advertising the capabilities of this engine.
3. The image is not a significant portion of the work; it is a portion of a single frame, and is at a much lower resolution than would be typical for playing the game.
4. Its use does not limit the copyright holder's ability to sell the work depicted.
5. It cannot (as of October 2007) be replaced with a free image, because the games that currently employ the technology are all distributed under non-free licenses.

[edit] Licensing

This is a screenshot of a non-free copyrighted video or computer game, and the copyright for it is most likely held by the company or person that developed the game. It is believed that the use of a limited number of web-resolution screenshots for identification and critical commentary on the computer or video game in question or the copyrighted character(s) or item(s) depicted on the screenshot in question on the English-language Wikipedia, hosted on servers in the United States by the non-profit Wikimedia Foundation, qualifies as fair use under United States copyright law, as such display does not significantly impede the right of the copyright holder to sell the copyrighted material, is not being used to generate profit in this context, and presents ideas that cannot be exhibited otherwise. See Wikipedia:Non-free content. To the uploader: please add a detailed fair use rationale for each use, as described on Wikipedia:Non-free use rationale guideline, as well as the source of the work and copyright information. Note: This tag should not be used for screenshots of free software; use the license tag corresponding to the software's license instead, optionally alongside {{Free screenshot}}.
