In the series Consumption & Renewal, Jiang Pengyi submerged copper sculptures and film negatives in a silver nitrate solution, allowing them to undergo mutual erosion for over six months. Through deep-focus macro photography, he captures the disintegration and reorganization of matter at a microscopic level.

As an irreplaceable technological medium, the photosensitive negative faithfully records the authentic dissipation of human traces within these chemical reactions. This collapse essentially reveals the decisive influence of the environment on the fate of matter: when the external medium undergoes irreversible change, do the traces we leave—and the technologies used to record them—gradually lose their distinct boundaries, ultimately drifting toward a state where "all back to dust".
