Stewart's imagery focuses on the wild rugged mountainous side of the Lake District and Scottish Highlands.
It is principally concerned with catching the fleeting and dramatic light that can play across the crags and ridges of the mountains at the extreme ends of the day; light that is capable of transforming an already enthralling scene into something remarkable and almost surreally beautiful. The interpretation is of an almost primal landscape devoid of human intrusion, the mountains as they have been for thousands of years and will continue to be for thousands more.
His photography represents a love of the solitude, wildness and quiet contentment that can still be found in the higher reaches of what is a relatively crowded and developed country.
Shortlisted for the Take a View Landscape Photographer of the Year award in 2010, Stewart's work features regularly in national magazines and guidebooks.
