Nature photographer Frans Lanting — best known for his wildlife images in books and magazines such as National Geographic, Life, and Audubon — has recently completed a huge project that looks backward and forward at the same time. Begun more than seven years ago, LIFE: A Journey Through Time is just that: Lanting looks at the vast subject of life on Earth via selective images of natural phenomena, what he calls "slices in time." Taschen has just brought out a lush coffee-table book by that title, and a traveling exhibit opens September 22 at the natural history museum in Leiden, Netherlands. But the project also has high-tech applications: A dedicated Website, www.lifethroughtime.com, is slated to launch September 15, providing an interactive, flash-driven companion to the book. And Lanting collaborated with composer Philip Glass to create a multimedia orchestral performance called LIFE MUSIC, in which the imagery is merged with a live symphonic rendention of Glass's score.
