How to cite a photograph:

Photographer, P. (Year of publication). Title of photograph [Photograph]. Source. URL

Example:
Ryan, S. (2019). [Sea smoke on Lake Michigan] [Photograph] New York Times. https://www.nytimes.com/interactive/2019/world/year-in-pictures.html

Note: if the photograph does not have a title, describe the photograph and put that description in square brackets. In most cases you won't know the photographer's name. I would recommend doing the following in that case:

[Sea smoke on Lake Michigan] [Photograph] New York Times. https://www.nytimes.com/interactive/2019/world/year-in-pictures.html
