One of the first photo books I ever got was Salgado’s “Workers” about 20 years ago. It has remained one of my all time favourites. So seeing the large gallery prints of those images is an absolute revelation. The scale is even more heroic and sorrowful than in the publication. There is an added dimension in these large prints that is missing from the book and that is the level of abstraction in the images which can only be fully appreciated when presented in a gallery setting.
