The primary ethical obligation of a documentary photographer is to capture the truth, as objectively as possible.

Documentary photography is typically more focused on social issues and long-term stories, while photojournalism is more focused on current events and breaking news.

Documentary photographers may face a number of ethical issues, including the need to balance the truth with the need to protect the privacy of individuals, the need to avoid bias and manipulation, and the need to avoid sensationalism.

The best way to avoid bias and manipulation in documentary photography is to be aware of your own biases and to try to overcome them, to research the topic thoroughly and to understand the different perspectives, and to talk to people from all sides of the issue.

The best way to protect the privacy of individuals in documentary photography is to get informed consent from the individuals before photographing them, to avoid photographing people in private settings, and to blur the faces of individuals in photographs.

The best way to avoid sensationalism in documentary photography is to avoid using graphic or shocking images, to avoid using emotionally manipulative language, and to avoid making generalizations about entire groups of people.

Violating the ethical principles of documentary photography can have a number of consequences, including loss of credibility, legal liability, and damage to the reputation of the photographer.

Documentary photographers can promote ethical practices by joining professional organizations that promote ethical standards, by speaking out against unethical practices, and by educating the public about the importance of ethical documentary photography.

The audience plays an important role in maintaining the integrity of documentary photography by being critical of the images they see, by asking questions about the context of the images, and by supporting photographers who are committed to ethical practices.

The future of documentary photography is uncertain, but it is likely that it will become increasingly important as a way to document the world around us, that it will become more difficult as it becomes more difficult to access people and places, that it will change as new technologies emerge, and that it will become less important as people increasingly get their news and information from online sources.
