Fog is nothing more than ground-level clouds. Here I was looking at the distant mountains through veils of cloud, where details showed in two bands: the middle distance and the foreground. In the middle distance I saw textures, while everything around that ridge was foggy and indistinct. In the foreground I saw not only detail but crisp, bright green shapes. There is no ‘focal point’. I don’t believe that all art needs one. What art needs, in my view, is a sense of atmosphere and features — whether of colour or shape or both — that intrigue the eye.
