The photographer artist Sow Cyan revisits Prussian blue, this iconic hue obtained through a fascinating chemical process born in the 19th century. As part of Autumn of Science, the Jacqueline de Romilly Library presents compositions where solar light replaces the camera. These creations prioritize direct contact between plant life and sensitized paper, revealing botanical silhouettes of spectacular delicacy. Between rigorous documentation and a waking dream, each work captures the essence of living things through enchanting chromatic reactions. Here, science becomes poetry, offering a fresh perspective on the fragility of nature. This handcrafted work, exhibited within the library, testifies to a striking modernity while paying homage to the pioneers of monochrome photography.
