Several years ago, at an American Geophysical Union meeting in San Francisco, I was mesmerized as a scientist showed repeat photos of natural places now versus decades ago. The glaciers in particular were shocking in their dramatic retreat. Such presentations focused on different regions have become a staple of AGU meetings, but they have been less accessible to non-scientists.
Two years ago came the tempting book Repeat Photography: Methods and Application in the Natural Sciences, edited by Robert H. Webb, with then and now photos. However, it’s more of a technical book about repeat photography’s scientific applications, and its $75 price reflects that.
