This week we started the shooting of a movie that will present the activities of the Image Guidance Lab at the Humboldt Forum in Berlin. Thomas Picht asked for my contribution as an ethnographer to the project. Recognizing an apt opportunity for intervention and invention with these research partners, I negotiated (not long, fortunately!) to combine this short project with a longer ethnographic video project. George Marcus labeled this kind of opportunity as a “para-site” (2000): a space aside from the everyday life of the community that I am observing, in which we are given the chance to think and perform together, and by doing this, to build a shared understanding the reality of the collective research at the lab and present it to the world.
