I've always had something of an admiration for those who work at heights. Not only do such people need to master the technicalities of their job, they also have to overcome the difficulties of doing it high above the ground. Consequently, when I see workers engaged in in this way and in this kind of location, I invariably take a shot or two of them. I've photographed wind turbine engineers, big wheel erectors, church spire repairers and conservation workers. I came across the latter again quite recently. They were on the west front of Salisbury Cathedral and seemed to be checking the statues and carved stonework, removing any loose debris.
