The Camera Axe is a popular device that synchronizes the camera and flashes for high-speed photography (think bullets and popping balloons). I use long extension wires to connect the lift-off sensor to the Camera Axe and a shorter shutter release cable to connect the Camera Axe to the camera. Actually, the Camera Axe has two camera ports, which I use to trigger two cameras, thereby capturing the same rocket lift-off from different angles!
I use “Advanced Sensor” mode with the following configuration:
|Setting||Device 1 value||Comment|
|Trigger sensor||Sensor 1|
|Delay ms||150||Increase delay to capture rocket higher on launch rod|
|Bulb sec||0.5||Let camera take 3-4 shots|
|Trigger type||Low||Trigger on voltage change from high to low|
|Retrigger||5||Suppress false positives|
