There are fewer than a hundred people in Bells steps but the composition is similar to that of a Salgado picture of gold-mine workers in Brazil. There’s a lot of tangled hair here and a general feeling of twistiness contributed by the low stems and branches; one-third of the picture is vegetation. Obviously it was hard to get a comfortable seat on the dune – the spectators are perched, slipping uncomfortably down, and it was clearly cold, but as far as the image – which would make an excellent jigsaw puzzle – is concerned, the people are distributed in pleasing clumps around the steps.
