How to cite a photograph
Follow any style requirements associated with your project.
If you're citing a photograph for a school paper or a formal publication, you might already be expected to follow a particular citation format. Consult with your teacher, professor, school, publisher, or supervisor to find out if they have a preferred citation style.
If you live in the us, the most common citation styles are apa (american psychological association), mla (modern language association), and cms (chicago manual of style). Determine your citation style based on subject.
