Purchased at Monod Sports in Banff, Alberta, this camera was used to record and to photograph poster sessions at the International Snow Science Workshop 2014 (Banff) as well as to photograph and document certain aspects of the CSTMC collections (Ottawa). An example of a wearable, point-of-view (P.O.V.) high definition consumer video camera aimed at the sports and action enthusiasts, the camera is also used by professional film makers as well as other users that require the filming of fast action. Founded by Nicholas Woodman in the USA but “Made in China”, the GoPro was first introduced in Canada about 2004 as a 35mm wrist mounted camera. Today the GoPro line of cameras is used by consumers worldwide and responsible for the “GoPro phenomena” in which users share and upload their mostly sports action footage on several social media outlets such as You Tube, Vimeo, etc. Other uses in Canada have been video surveys conducted by wildlife biologists and in law enforcement. Police forces from Edmonton, Calgary, Vancouver, Toronto, and Ottawa have been experimenting with body-worn video (BWV) cameras. The Vancouver police is experimenting with the GoPro as part of the Oppenheimer Park eviction. "The force is using devices manufactured by GoPro, which makes small video cameras that have become popular among extreme sports enthusiasts. The cameras are small, waterproof, nearly indestructible and can be mounted just about anywhere". (From Worksheet, Ref. 1)

Technique

An example of a consumer digital video camera, this Wi-Fi enabled wearable camera records high definition point-of-view sports and action videos and still images on a micro SD card up to 64 GB. The P.O.V. technique in cinematography (Mascelli, The Five C's of Cinematography, 1965) allows audiences to see events through the filmmakers eye. Calling upon all the benefits of video camera miniaturization and a full suite of mounting accessories (head, helmet, chest, wrist, and dog harness and straps, clamps, handles, handlebar, seat post, roll bar, suction cups and tripod mounts), GoPro introduced the Hero camera in a market which had few specialist P.O.V. or “wearable” cameras. At the heart of the 74g camera is a Sony 12MP Exmor-R imaging sensor capable of 12Mp imaging up to 35 fps and supports 4K and full HD output , an Ambarella A7 single chip H.264 video compression codec, and an f/2.8 fixed aperture six-element aspherical wide-angle glass lens. In video mode, users can select from nine resolution options, from 15 frames per second (fps) in 4K, 60 fps in 1080p, or up to 120 fps in 960p, to name a few. In photo mode the Hero3+ shoots at 12MP, is capable of shooting 12MP burst photos at 30fps, and can shoot time lapse at 0.5, 1, 2, 5, 10, 30, or 60 second intervals. The feature-set also includes “Protune”, a cinema-quality video mode for professionals; “Super View” fixed ultra wide angle lens, and “Auto Low Light” which automatically adjusts frame rate to low light performance (see the appendix for full list of specifications). The Black Edition package includes the Hero3+ camera, waterproof housing to 40m, high capacity Li-ion battery, Wi-Fi remote, and assorted mounts and hardware. A multitude of accessories make the Hero line of hands-free action cameras usable from any point of view, where the subject is the actor and filmmaker. GoPro does not manufacture components itself but rather sources them from several manufacturers. Removal of the battery cover reveals “Made in China”. A teardown of the Hero3 camera provided by Chipworks and iFixit however reveals IC circuitry from at least seven different manufacturers, and a difficulty in tracking their manufacturing country of origin. Below are highlights to the chip set found on the motherboard (see Worksheet in Supp. Info.). A more detailed analysis can be found in the Appendix and Inside the GoPro Hero3 Wearable Sports Camera (Chipworks, 22.01.2013). (From Worksheet, Ref. 1)
