[Design-team] Wallpapers guidelines draft

[William Jon McCann]

Hey,

So as we discussed on IRC.  Attached is a draft of some guidelines for
artwork submissions and specifically desktop background contributions.
 Parts of it are derived from the existing guidelines [1].  I'm hoping
this will help us:
 * Clearly define the legal rules for submitted works
 * Give some more explicit guidance to potential contributors
 * Establish some general guidelines to frame the decision making process

What do you think?

Thanks,
Jon

All submissions or contributions:

 * Must be covered by the Contributor License Agreement.
   We cannot accept contributions from individuals who have not signed the CLA in the  Fedora Account System. The CLA allows us to properly license artwork submissions for distribution with Fedora and other Fedora projects.

 * Must not contain material that violates or infringes another?s rights, including but not limited to privacy, publicity or intellectual property rights, or that constitutes copyright infringement;
   If your submissions include or derive from artwork created by other people, please make sure the license of the original work you incorporate is compatible with Fedora and that you are not violating any of the provisions of its license. Just because a work is licensed with a Creative Commons license does not mean it is free to use (make sure you provide attribution to artists that license their work with a CC Attribution clause.) 

 * Should have the consent and approval of the author or creator

 * Are thereby licensed to the public for reuse under CC-BY-SA unless specifically identified as being licensed by another approved liberal open source license.



Subject matter:

 * Must not contain brand names or trademarks of any kind

 * Must not contain material that is inappropriate, offensive, indecent, obscene, hateful, tortuous, defamatory, slanderous or libelous
   - No sexually explicit or provocative subject matter
   - No images of weapons or violent imagery
   - No alcohol, smoking, or drug use imagery

 * Must not contain material that promotes bigotry, racism, hatred or harm against any group or individual or promotes discrimination based on race, gender, religion, nationality, disability, sexual orientation or age

 * Must not contain material that is unlawful, in violation of or contrary to the laws or regulations in the jurisdiction where the work is created

 * No religious, political, or nationalist imagery (including flags)

 * No images of hats, particularly fedoras.
   This is a matter of respect for our primary sponsor, Red Hat, Inc., and is not negotiable. Of course, passive appearance of hats, such as those upon heads in a crowd, may be allowed. 

 * No version numbers.
   End users might prefer to continue to use an older theme, or use the latest theme in their older version of Fedora. To enable that choice, do not use any version numbers within the Fedora artwork. 

 * No text.
   Text should not be used in the backgrounds because the artwork is intended for a global audience and to be reused by derivative distributions.

 * Should not contain images of people (contemporary, historical, or fictional)

 * Should not contain images of pets, or captive or mistreated animals



Technical requirements:

 * Must use a format that can be read by software available in Fedora Package Collection
   Preferred image formats include SVG and PNG.  Master files, which may be further edited, should be maintained in non-lossy formats. Preserving vector graphics, raster layers, and channels is important for such materials. 

 * Originals for landscape formats must be a minimum of 1600 pixels wide and 1200 pixels high
   The larger the better.  Photographic submissions should be made at the highest resolution the camera is capable of.

 * Should be provided in a 16 x 9 aspect ratio

 * No watermarks, signatures, photographer/creator names, or messages may be included in any part of the work


Composition:

 * Should strive for subtlety and poetry
 * Avoid high frequency images
   (http://forensicphotoshop.blogspot.com/2009/04/low-frequency-vs-high-frequency.html)
   - A soft focus is one way to achieve this
 * As the name suggests, visually, it should settle into the "background" of the activity scene.
 * Fewer details on left side allows for good readability for primary icons on the desktop.
   - Keep in mind that many users have icons covering the entire desktop view.
 * Do not compete for the user's attention

Specific guidelines.

 * Default background:
  * The following adjectives should be used to select an appropriate design:
   - Fresh
   - Light
   - Calm
   - Clean
   - Modern
   - Harmonious
   - Unfettered
   - Elegant
   - Graceful
   - Hopeful
   - Delightful

 * Additional Themes:
  * May use following categories:
   - Nature
   - Landscapes
   - Cosmos
   - Scenes
