Water is not mere embellishment; it is the essence of my reverie." So says Felix Davey, a Belfast-born photographer so inspired by the sense of freedom he finds in all things aquatic that last year he was drawn to Scotland's west coast to seek out those he dubs the "Water Folk" – people for whom water is enmeshed in their lives. "These individuals' solitude and fortitude," he says, "speak of wild, beautiful places, and our place within them."
