How does it work?

According to an article published in Sport Fishing, "the GoPro Hero is sold with a bevy of mounting accessories, as well as a waterproof housing that keeps the camera safe and bone dry."According to another article published in Popular mechanics, when the idea of such a camera first came to Woodman's mind, he was mainly thinking about creating "a wrist strap with a mechanism that pivots the camera out of the way while he was surfing, pop it up for the money shot, and then fold it down again." He wanted it to follow every single movement he made, and without worrying about carrying it or protecting it since it is shock resistant. According to the same article, "GoPros are small, light, and waterproof -- and their signature wide, nearly fish-eye lenses seem to magically make subjects look, well, more heroic than they might otherwise be. That wide lens shoots your knees and skis, or your hands on the handlebars of a bike. The result is a big, immersive, ego-enhancing image. GoPro cameras are structurally designed to flip the traditional relationship of cameraman to subject, aligning it more closely with the way people shoot video in the YouTube era. The cameraman is the protagonist of his own video, and the lens stretches wide enough to fit in both him and the world he is conquering." Surely, this is the reason why the GoPro camera is known as the best "action" camera: because it takes photos at the heart of the action, making them look completely real and alive. In fact, there is an article published in Information Technology Newsweekly explaining that a GoPro comes with "various straps, pivot arms, and adhesive mounts to enable the digital camera to capture images while performing activities such as biking, skiing, skating and kayaking." However, there are different generations of GoPro, going from the HD HERO to the HERO 3+, and depending on the generation it belongs to, a GoPro camera may have different characteristics. Indeed, according to the same article published in Information Technology Newsweekly, the HD Hero2 camera for example "includes only a single image capture system, which captures images using an optical axis directed outward from the 'front' of the camera. This can cause excessive wind resistance and presents a high profile that is more susceptible to damage and image artifacts from vibrations in some situations." Sport Fishing also published an article about the HD Hero 2 saying that it is "twice as powerful as the original." The author of the article goes on specifying: "The HerO2 shoots 1080p HD video and 11-megapixel stills. The camera's new processor delivers the additional power, and the redesigned wide-angle lens takes full advantage, providing ultra sharp imaging. The HERO2 captures up to 10 11-megapixel photos per second and comes with an LCD interface." According to the GoPro website, there is another difference between the old GoPro cameras and the new one and it is that the first ones' battery life was much longer than now. The camera comes with an USB cable, and so it is easy to transfer the photos to a computer. Also, in order to improve the sound quality, we can change the backdoor of the camera - if we are not going to put it underwater- for another backdoor that has holes in it. There is also a floating backdoor that we can use when we go under water, and that keeps the camera on the surface of water in case we lose it. According to an article published in Bloomberg BusinessWeek Magazine, the HD Hero3 camera even comes with a Wi-Fi remote, to which we can connect it and it allows us to control the camera from distance using an iPhone or Android app.
