Repeat Photography

Book excerpt: First developed in the 1880s as a way to monitor glaciers in Europe, repeat photography —the practice of taking photographs at different points in times from the same physical vantage point—remains an essential and cost-effective technique for scientists and researchers working to track and study landscape change. This volume explores the technical and geographic scope of this important technique, focusing particularly on the intertwined influences of climatic variation and land-use practices in sculpting landscapes. Contributors offer a broad-perspective review of the state-of-the-art of repeat photography, with twenty-three chapters written by researchers around the globe who have made use of repeat photography in their work. Topics addressed include the history of repeat photography techniques for creating and analyzing repeat photographs applications in the geosciences applications in population ecology applications in ecosystem change cultural applications Repeat Photography demonstrates the wide range of potential applications, examines new techniques for acquiring data from repeat photography, and clearly shows that repeat photography remains a valuable and efficient means of monitoring change in both developed and developing regions. Over one hundred sets of photographs, including thirty-two pages of color photos, serve as examples. Recent concerns about climate change and its effects on natural landscapes, combined with ongoing concerns about land-use practices, make this state-of-the-art review a timely contribution to the literature.
