The HERO3 is GoPro’s newest action camera. I tested the most capable version, the Black Edition, with the new optional LCD Touch BacPac and the new minimal-design housing, The Frame. The optional LCD Touch BacPac allows you to frame your shots properly and command the unit.
No photography gear I know of chews through AA batteries more quickly than external flashes. These little technological marvels are awesome, but their onboard power and recycle times can quickly become frustrating. Until now, auxiliary power solutions have been bulky, expensive battery packs that can be burdensome to carry or securely attach.
