Licensing[edit]

This photograph of a three-dimensional object is in the public domain in Switzerland (Art. 29 par. 2bis of the CopA), because the photographic depiction was created at least 50 years ago and the reproduction has no individual character.

The template should only be used if no other license is possible.
 
A photograph without an individual character uses the creative freedom neither in terms of photo technology nor in conceptual terms, but does not stand out from the generally accepted.
This license cannot be used for photographs that express an expression of thought with an individual character. This is possible, for example, by selecting the image section and the time of shutter release, by setting the focus and exposure, and by processing the negative. The distinction between photographs with and without an individual character is not always clear.
