GoPro is gaining in consumer popularity thanks to its collection of Hero Camera mounts that allow users to attach inexpensive cameras to everything from ski helmets to the tips of surfboards for action footage. Already popular with skiers, snowboarders, surfers, bikers and other outdoor enthusiasts and extreme athletes, the GoPro line is starting to become more common with professional cameramen as well. Nature photographers, in particular, are using GoPro products to shoot footage of hard-to-reach places, such as inside a cobra’s den or a shark’s mouth.

The small, six-ounce, 1080p camera comes with a water-tight housing and starts at $260.

GoPro’s parent company, Woodman Labs Inc., is receiving funding from outside investors, including Steamboat Ventures, a venture capital fund backed by Disney (Steamboat Ventures was also an investor in Pure Digital, maker of the popular Flip pocket camcorder). Steamboat plans to help GoPro expand further into the professional market.

Gizmodo offers a positive review of the 3D Hero System — a $99 3D kit (cameras not included) that GoPro bills as “the world’s smallest 1080p 3D camera.” The system combines two HD cameras in a waterproof housing that enables users to shoot synchronized photos and video (2D and 3D) that can then be edited in 3D with the free CineForm Studio software.

Most helmet and similar cameras have gone to wide angle lenses to ensure footage and minimize shake. The result was effective, but made things look smaller when viewed. Gizmodo notes that “adding 3D gives depth to the trees and objects rushing past you,” providing for a more immersive viewing experience.
