Whitaker's work explores how photographs can network, participate in systems, iterate, and form relationships. The book alternates between one full-page photograph and up to four on the next page that relate to the first. By adhering to this organizing principle and by employing repetitive marks made through in-camera masking, the photographs assert a linearity more typical of text than image. The cover spells out the book's title and author using an illegible alphabet, which, inverting the logic of the photographs, asks to be looked at rather than read. Peer to Peer includes an accompanying text insert written by Aaron Kunin.
