7. Adjust the “sensitivity” setting using the slider. Make sure the sensor value is
greater than the threshold (middle of the arc) when laser beam is feed to the
laser sensor. And also make sure the sensor value is smaller than the threshold
when you break the laser beam.
8.
Use the “trigger mode” button to switch between “High trigger” and “Low
trigger”. In “High trigger” mode, the trigger fires when the laser beam is feed
to the sensor. Whereas in “Low trigger” mode, the trigger fires when you
break the laser beam.
9.
Use the “trigger speed” button to switch between “High speed” and “Power
save”. In “High speed” mode, the trigger fires with the response time less than
20 microseconds. Whereas in “Power save” mode, the trigger is slowed down
to a response time of 1 millisecond to save battery power. One millisecond
response time is still very fast comparing with the shutter delay of your
camera, which is usually tens of milliseconds. In one millisecond, Usain Bolt
can only run a distance of 1cm. As a rule of thumb, use “High speed” when
trigger flash, and use “Power save” when trigger camera.
10. Use the “delay” setting to delay the triggering of your camera or flash. The
unit can be set to microsecond, millisecond and second.
11. Press red "Start" button to run the program.
5.2. SOUND MODE
The sound mode is used for high-speed photography where your regular DSLR
camera is too slow to take pictures of popping balloons, breaking glasses,
exploding items etc. The idea behind using a sound trigger is very simple. Instead
of triggering your camera, you are going to trigger the flash unit. Your camera will
be in bulb mode in a completely dark room. Whenever the flash is triggered, you
will capture a single frame. Instead of taking many pictures with a high-speed
camera, you will capture a single frame with your regular DSLR camera. In this
setup, the speed of the flash unit is also very important. The faster the flash unit,
the sharper will be the image.
