Together with Marco de Mutiis, our article on in-game photography got published as part of the book
Fuchs, Michael, and Jeff Thoss, eds. 2019. Intermedia Games–Games Inter Media: Video Games and Intermediality. New York: Bloomsbury Academic.
So, in case you are interested in learning about different types of in-game photography, please have a look at
