    Forum introduction

    This is a draft introduction for a proposed Forum in the journal Environmental History, with articles from various contributors about doing repeat photography on a mass scale. (500 words)


    The rephotography cycle will never scale up without serious archives. Here is a proposal for one, plus the story of how it did not happen. (4,000 words)

    “The big picture is this: if we are going to do mass rephotography– if we are going to reconstruct the Earth’s landscape through time– we need to get a clue about organizing those millions of photographs. We need, among other things, to graduate from loose sheets to books.” (images + 5,000 words)


    This article is a demonstration of prephotography at centifluences. That is, shooting landscape photos intended to be reshot later, and doing so on a half-mile grid. It uses the example of a forest fire in the Black Hills. Also, a note explains why these photographs were not shot using rephotography software: because it does not exist. But such software is not hard to imagine. (images + 5,000 words)

    Rephotography 101

    This lesson plan lays out one way to start students in rephotography, by spending one class period using their phones to reshoot old photos of their campus. (PowerPoint file, 22 MB)

    Google Earth Gobstoppers

    This one is a little trickier, but you should be able to get it to work. This demo of photo stacks as floating spheres is an illustration referenced in the “Gobstoppers” article above, but you need the Google Earth Pro “browser” to see it. (You don’t need a 3D mouse like a SpaceMouse / SpaceNavigator, though it’s more fun with one.) In Google Earth Pro, click Add > Network Link and paste this address into the “Link:” field: You can also download this zipped folder if you’d like to handle these files more quickly on your own hard drive.
