Nick Paumgarten has written a great piece for The New Yorker on the history and significance of the GoPro camera. This is really worth reading, whether you have or use a GoPro camera or not.
Woodman had the good fortune to invent a product that was well suited to a world he had not yet imagined. The ripening of the technology in his camera, after a half decade of tinkering, coincided with the fruition of broadband and the emergence of YouTube, Facebook, and other social-media platforms for the wide distribution of video. GoPro rode the wave. What might have been just another camcorder became a leading connector between what goes on in the real world and what goes out in the virtual one—a perfect instrument for the look-at-me age. Its charm lies perhaps in its sublimated conveyance of self, its sneaky tolerable narcissism. GoPro footage is related to the selfie, in its “Here I am” (or “was”) ethos, and its wide view and variety of mounts often allow the filmmaker to include himself, or some part of himself, in the shot. But because it primarily points outward it’s a record of what an experience looks like, rather than what the person who had the experience looked like when he stopped afterward and arranged his features into his pretested photo face. The result is not as much a selfie as a worldie. It’s more like the story you’d tell about an adventure than the photo that would accompany it.
