Every photograph on this site is used under Creative Commons Zero, the public domain, or a Creative Commons attribution licence. Each one is shown here with the description its source gives it, so you can check that what we say a photo shows is what the photographer said it shows.

9 photographs, 4 of them under licences that require the creator to be named. Those credits also appear next to the image on the page itself. Nothing here is stock photography bought for atmosphere. Where a page shows a photo, it is because the photo carries part of the argument.

Share-alike licences (CC BY-SA) cover each photograph; this site’s text and code carry separate rights. If a photo here is mislabelled, misattributed, or mismatched with its description, tell us and we will correct or remove it.
