Cityscape Panorama Project

Went to a lecture/presentation recently by an architectural photographer named T. John Hughes.  He has been working on creating a visual record of Downtown Denver, every five years, since 1992.  The process, known as "rephotography", takes images from the same vantage point to illustrate changes in the urban fabric.  His work is important for designers in charting the incremental progress of architecture, as well as society.  Too often, we refer to buildings in "eras" or very large chunks of time.  Hughes brings the interval down to five years, which I believe allows us to put change in terms of our lifetime, instead of generations.  His work can be viewed on the website: http://cityscapepanorama.com/
