Pluto Trigger is a high-speed smart camera trigger that's controlled by a iPhone/Android app wirelessly that can be used for remote shooting, time lapse, HDR, video recording and lightning photography.
It enables your DSLR to do high-speed photography triggered by sound, by light, or by something breaking a laser beam aimed at the Pluto Trigger. It can detect animals' body heat and take photos.
It can also wait until a person is smiling to shoot a photo, or take pictures triggered by motion or vibration. You know those fancy photos of water droplets colliding in mid-air? There's a mode for that too. See all the 24 modes.
