Fair use rationale for use in the article Comet Elenin


Even though the media C2010x1 20101211.jpg is copyrighted and not released under a free license, I, ZooGuard, feel it is covered by fair use for at least one of the following reasons:

  • No free alternative exists.
    • This image does not limit the copyright owners' rights to distribute the original image in any way.
  • This is a JPEG image intended for distribution on the Internet with the resulting loss of quality and not the original image in a lossless format (such as FITS).
  • This image was not altered in any way and the original attribution information is still a part of the image.
  • This image is intended to refute a widely spread misrepresentation of the original work of the authors.
  • The placement in a RationalWiki article is being used for informational purposes only, and its use is not believed to detract from the original copyrighted media in any way.
  • A free alternative may not exist now, but in the event of a free alternative being located for the article "Comet Elenin" in the future, this file should be deleted as soon as possible.
