Andrea Moretti has been a professional photographer and speleologist for about twenty years. His photographic work has always focused on people, their work, and their faces. Recently, his research has led him to explore the contrast between light and shadow in the underground world, capturing darkness and the cave sections illuminated by his fellow adventurers. A supporter of photography that represents reality as we see it, rather than as we would like it to be, Moretti creates images where people are not mere spatial references but protagonists, bearers of light in the darkness.
