Bernard Plossu's Jardin de poussière, first published in 1989, offers an intimate, poetic vision of the American desert. Through small black-and-white prints close to the daguerreotype, Plossu captures the subtlety and mysterious essence of these arid landscapes, made between 1981 and 1985 during walks through Arizona, New Mexico and Utah, testifying to a personal, spiritual quest. Rejecting spectacular grandeur, he favours a minimalist, stripped-down approach celebrating the discreet beauty of natural elements, the desert, presented as a "garden of dust", embodying both fragility and resilience, a vital space to be preserved.
