Repeat Photography: History and Practical Ecological Applications

Repeat photography is a technique which involves taking multiple photographs of the same subject, from the same location, at different times. First used as a scientific tool at the end of the 19th century to study glacier change in the Tyrolean Alps, its use spread to North America with the advent of surveying for route mapping and railway construction. In Canada, surveyors developed their own photo-topographic survey methods to map the high mountain peaks and passes of the Rocky Mountains. The photographic legacy of those surveys still exists today in what is known as the Mountain Legacy Project: the world’s largest collection of historical and repeat photographs of mountain landscapes.

Sonia Voicescu is a PhD Candidate at the School of Environmental Studies, University of Victoria. She is currently part of the Mountain Legacy Project research group and her research combine principles of ecological restoration with elements of environmental history to investigate ecological and cultural changes in highly disturbed mountain ecosystems.

This presentation will provide a brief overview of the history and basics of repeat photography and discuss how this technique can be used to assess ecological changes in different ecosystems. Three repeat photography projects will be described, with a focus on the Mountain Legacy Project methods and research outcomes.

This presentation will be aired via Zoom Video Conferencing. On the Mondaypreceding the event, Nature Vancouver members will receive the Zoom link in the weekly e-News. To join the talk on Thursday, click on that link after 7:15 pm. The talk will begin at 7:30 pm.
