Takuma Nakahira's book explores his experimental project from Paris in 1971 during a biennale that attracted young artists globally. Nakahira's work sought to challenge the concept of expression by documenting reality indiscriminately, focusing on 'date' and 'place,' and immediately recirculating these elements within the same reality. This project marks the initial realization of his unique photographic methodology. The book delves into this theme through extensive illustrations, presented in both Japanese and English, offering an insightful look into Nakahira's approach to photography and his innovative exploration of what defines artistic expression.
