It's been a long time coming (twelve years!) but the book Scott Brady and I have been working on is finally done. It's called Phantom Skies and Shifting Ground: Landscape, Culture, and Rephotography in Eadweard Muybridge's Illustrations of Central America. It's co-publication between Temple University Press and Radius Books and is now available for purchase: http://www.temple.edu/tempress/titles/2415_reg.html
Radius books did a beautiful job designing the book and it even includes a small portfolio of separately bound Muybridge photographs in the front section.
In related news, Places Journal, a wonderful site for scholarship on architecture, landscape, and urbanism published an abridged version of my essay from the book. It can be found here: https://placesjournal.org/article/eadweard-muybridges-secret-cloud-collection/
And if you want to get a sense of the entire scope of the project, including animations about Muybridge and the wacky things he did with clouds, visit Phantomskies.com, a companion web site I made with Temple University Press. It's an experiment in open source publication that allowed me to show some more kinetic versions of creative work from the project.
