Getting the most out of your high-end DSLR — like taking pro-quality time-lapse shots or long exposures — is a lot easier when you're using a remote. But why blow a bunch of cash for some standalone remote when you've already got smartphone that'll do the same with a TriggerHappy adaptor?
The TriggerHappy remote is a 1m cord that connects the camera's input port to the the phone's 3.5mm audio jack via a small embedded signal processor. Using either the Android or iOS app, users can perform pretty much anything you can imaging doing with a DSLR. According to the TriggerHappy site, this includes "single-shot triggering to time-lapse modes where the shutter length, interval, duration and number of shots per interval" can all be individually adjusted. It also includes some slick other features, such as the ability to snap shots based on phone's accelerometer activity, facial recognition, or lighting and audio detection (lights go on or someone makes noise, the camera will fire). It's even got an HDR mode.
It works with all modern Canon and Nikon DSLRs as well as a broad variety of other brands, depending on the adaptor used. The project has already doubled its Kickstarter goal of $US25,000 with 44 days to go so a $US50 donation is guaranteed to net you a remote when the project funds. [Kickstarter]
