Rather than using sound mode as a normal non high-speed sound trigger,
here we will mainly focus on using it for high-speed photography.
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.
The sound mode has two parameters. These are Sensitivity and Delay. The
sensitivity can be set to a value between 1 and 100 using the dial. Setting
the sensitivity to a high value will let you to capture more sound events. If
you want to capture only high level sound events, you need to set the
sensitivity to a lower value. You can try and see which sensitivity level fits
your needs. The second parameter is delay. The sound event may be
captured too early. So, you need to add some delay. The flash unit will be
triggered after the delay you specified and this will allow you to capture
the picture at the exact moment.
