Lovers of the Sierra wilderness, especially visitors to Yosemite and admirers of naturalist John Muir, who delighted in this area and described it so eloquently, will take much pleasure in this book. Hyde's landscape photographs are paired with selections from Muir's writings, as Eliot Porter's famous "In Wildness Is the Preservation of the World" paired his works with quotations from Thoreau. Porter's landscape work, and Ansel Adams', set the paradigms within which Hyde has produced his large body of landscapes, mostly of his beloved Sierra Nevada. This volume is actually something of a retrospective of Hyde's 50-plus years in the mountains. For Hyde, then, more's the pity that one photograph is printed upside down, one on its side, and one in lurid purple tones because of the fading of the film. Competent and sometimes quite beautiful, his photographs are not so much original as they are "good of their kind." "The Range of Light" may prove more valuable to those concerned with natural history and conservation than to those interested in photographic art.
