Unknown Quantities is a collection of zines from four different photographers, Olivia Arthur, Dominic Nahr, Moises Saman and Peter Van Agtmael. Each zine documents the time the photographer spent in a developing country. However, each focuses on very different political issue.
Arthur spent her time in Saudi Arabia, documenting the lives of women there and how they are mistreated. Nahr shows the uprising against former Egyptian president, Mubarak. Saman combines his own images with government images from the civil war in Libya. While Van Agtmael stays slightly closer to home, combining images from Iraq, Afghanistan and the USA.
The zine collection is presented in a small folder, similar to that used to file official government documents. This shows that the zine are focusing on important political issues. Is also gives a professional and serious feel that empathises the importance of the issues raised in within the folder.
