Grab your smart device, open up the app store, search for Triggertrap and then download the free app.
Connect the connection cable to your dongle.
The Triggertrap Mobile kit comes in two parts. You have the camera connection cable (a cable with a 2.5mm plug on one end and a camera connector on the other end) and the mobile dongle (the black box with the TT on the front). Connect the connection cable to the mobile dongle.
Connect the dongle to your smartphone
Connect the plug leading away from the dongle into the headphone port of your smart device (phone or tablet).
Connect the connection cable to your camera
Connect the other end of the connection cable to your camera. You’ll need to plug this into the remote port. On most cameras this is labeled with a small remote icon, but on some Nikon cameras it’s labeled ‘GPS’. If you’re not sure where to find the remote port on your camera, check the camera manual.
Set the camera to manual focus
Switch your camera onto manual focus. This is usually a switch on the body, lens or both.
Load up the Triggertrap App on your smart phone and turn the volume up
Turn up the volume to 100%. If you are using an Android device make sure that you’re turning the media volume up.
Open up the Simple Cable Release mode and tap the red button. When you tap the button, the camera should take a photo.
