Can I apply a Creative Commons license to software? We recommend against using Creative Commons licenses for software.

If I take a photograph of another work that is in the public domain, can I apply a CC license to my photo? That depends. You can apply a CC license to your photograph if your photograph constitutes a work of original authorship, a question that varies by jurisdiction. As a general matter, your photograph must involve some creative choices, such as background setting, lighting, angle, or other mark of creativity. In the United States, an exact photographic copy of a public domain work is not subject to copyright because there is no originality (even if there is effort or “sweat” exerted in its creation).
