The Triggertrap app that turns your iPhone, iPad or Android device into a remote trigger for your camera is now free. Previously, it was $4.99; however, it will be free at least through the holiday season. (Note that there is a limited-feature “free version” available, but this is the premium version that has now been made free.)
You need a $25 cable to make it work with your DSLR, but it does a whole lot more than a standard cable release remote for that price. I’ve used it with my Canon 5D Mark II and it works very well. Additionally, if you don’t get the dongle, some of the modes (like timelapse) will work with the iPhone’s built-in camera. So, it’s worth having for free anyway.
Below are some of the triggering methods you can use with Triggertrap.
- Multiple Timelapse functions: Use Triggertrap as a basic intervalometer for timelapse capture, or get extra creative: Bulb Ramping Timelapse enables seamless sunrise/sunset timelapses, HDR timelapse lets you combine the power of HDR and timelapses, and finally, TimeWarp, a feature unique to Triggertrap, uses algorithms developed for animation to create more dynamic and natural-looking timelapses.
- Sensor Controls: Leverages the smart device’s on-board sensors to release the shutter; Sound Sensor Mode uses the microphone to trigger at a set audio level, Seismic Mode fires based on vibrations, bumps or knocks, and Metal & Magnetism Sensor Mode can be used to fire the shutter in their presence
- Facial recognition: Takes a photo once Triggertrap detects the programmed number of faces in the frame
- Multiple HDR Capture Modes: Provides expanded control over bracketed exposures for Long Exposure HDR, or automates Long Exposure HDR Timelapse capture
- DistanceLapse: Unique to Triggertrap, this mode relies on the smart device’s on-board GPS chip to fire the shutter over pre-determined distances
- Motion detection mode: Triggers camera whenever motion is detected in the frame
- Star trail mode: Allows external cameras to automatically take a series of long exposures in sequence to reduce noise
- Wireless mode: Unique to Triggertrap, this new Wi-Fi triggering technology enables photographers to leverage the range and speed of a Wi-fi network to control the dynamic features of the Triggertrap Mobile app wirelessly
