Red Bloom is the second part of a photographic and artistic project devoted to global warming and, in particular, the proliferation of green algae in the Côtes d'Armor region of France. Through hundreds of images, Alice Pallot returns to the very essence of the photographic process: making visible what the human eye alone cannot perceive. In this series, she proposes to materialise the sun's red rays, which contribute to the development of toxic algae. Each work bears witness to an ecosystem threatened by the putrefaction of plants. The creation process takes several weeks: cultures grow on the prints and it is the toxicity itself that is embodied in the photograph and becomes the substrate for the algae. The artist's aim, through works of great plastic beauty, is to alert the viewer to the non-visible but nonetheless active and deleterious anthropogenic toxicity of our environment. Through the visual experience, the viewer gains a deeper understanding of this major issue of our time.
