Professional photographers and enthusiasts know how essential a solid trigger system is for a successful shoot.

Enter Trigger Happy, a smash-hit Kickstarter project that received its full funding today. Trigger Happy is a physical cable adapter and app combo that can control pretty much every function of your DSLR.
