I do not make my living as a photographer. Since I generally do not profit in retaining copyright, I release many of my photos under a free license that allows people to use them in a fair manner.

Understand, however, that this is license does not apply by default to any given photo. The contents of this page are only meant as a description of my usual licensing terms. Unless I explicitly give a license for a photo, it must be regarded as still under full copyright.

That said, here are the usual terms:

Free license
When I release a photo under a free license, it is under the GFDL 1.2 or the Creative Commons Attribution Share-Alike 3.0. If I do not specify the license version on a photo, it is automatically the version mentioned above. If you encounter a photo of mine that is licensed under an older version of said licenses, you are also permitted to use it under the versions listed above. If I have licensed a photo under one of these two free licenses, it is automatically available under the other as well.
Commercial license
From time to time I will release a photo under a commercial license. (The free licenses permit commercial usage, but most companies do not want to run a byline and license terms under the image, which would be required.) The license I provide in these circumstances is non-exclusive, royalty-free, perpetual, worldwide, non-sublicensible, and irrevocable. It is not permitted to affect my ability to create more licenses on the photo, or to affect existing licenses.
