Pluto Trigger is a high-speed smart camera trigger that's controlled by a free iPhone/Android app over Bluetooth LE(Low Energy) that can be used for remote shooting, time lapse, High Dynamic Range (HDR) photography, 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 (the laser is included). With the built-in PIR sensor, Pluto Trigger 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(Droplet Valve required) -- 24 Modes in all. 

Pluto Trigger has infrared(IR) remote control capability, which enables it to support a wide variety of cameras (not just DSLRs). The app can even calculate depth of field, shutter speed when using an ND filter, 500 Rule and Sunrise/Sunset Time!
