Predominantly, "Southam's subject is the rural landscape of the South West of England, where he lives and works."[1] He conducts long-term studies of selected sites, that trace changes over seasons and even several years. His first project, in black and white, was The Floating Harbour: a Landscape History of Bristol City Docks (1977–84). All subsequent series are in colour and include Paintings of the West of Cornwall (1982–86); and The Long White Cloud, made in New Zealand at the end of 2018.[10] He uses an 8×10 large formatview camera.[12]
