GoPro cameras allow action-sports enthusiasts to take professional-quality videos. Of the million or so HD Hero2 cameras the company sold in 2011, many were purchased by consumers who don’t have thrill seeking on their minds. Couples are leaving them on tables at weddings instead of disposable cameras. Elizabeth Henriquez, a physics teacher at Bergen County Technical Schools in New Jersey, puts GoPros on blindfolded kids and asks classmates to guide them through an obstacle course to give her students a sense of what it’s like to operate the Curiosity rover on Mars. Fire departments use them for training purposes, marine biologists use them for undersea research, and the U.S. Army uses them in tests of the damage to Humvees from roadside bombs.
On Oct. 17, Woodman Labs introduced a new model called the HD Hero3 that’s 25 percent lighter and 30 percent smaller than its predecessor. It offers better resolution, clearer audio, and slower slow-mo.
