'Mediations' by the American photographer Susan Meiselas proposes a selection of works from the 1970s to today, revealing Meiselas’s special approach to the underlying reasons for making photographs, how the image concerns its subject as much as the photographer and the role that these images can have at different levels in society and particularly in photojournalism. She questions the relationship between the image and the subject in such a way as to include the people portrayed in the image in the image-making process. There is nothing systematic in her approach: each work expresses in a very strong manner the notion that context is vital to the understanding of photography.
