Are there other ethical guidelines which should be followed?

Images that purport to be “news” photographs, reporting, photojournalism, or documentary photography, should comply with the ethical guidelines of the National Press Photographers Association (https://nppa.org/code-ethics) in general, as well as those proposed by UNICEF for ethical reporting on children (https://www.unicef.org/eca/media_1482.html). No people or objects may be added, rearranged, reversed, distorted or removed from such photographs. If images are staged, this should be made clear in the written statements and captions. It is important, always, to take into account the ethical considerations of photography, and to protect vulnerable people from potential harm that could be inflicted as a result of publishing images that expose or identify individuals or groups who may be or may become vulnerable as a result of the publication of the photographs.
