Nero Trigger: The Sound Sensor
The Sound Sensor
I had the opportunity to test the sound trigger on the Nerotrigger today and as I suspected the ability to be able to precisely set the delay on the Nerotrigger is hugely beneficial. For this series of tests there really was no need to take any practice shots to perfect the timings, all I needed to get right was the sound sensitivity setting, very easily done by firing off a couple of poppers. Once that was set correctly I only had to get the lighting and camera settings to my liking. This was achieved just by placing a popper in situ and checking that focus and lighting was ok and taking a couple of images to review on the camera. The following demonstration shots were taken at 5ms intervals , the first being set at 2ms delay from the 'pop', then 7ms, 12ms and finally 17ms. I elected to use party poppers, with a small amount of flour added to each one, to do the test as I was able to replicate each shot quite easily. This is of course just about scratching the surface of what the sound trigger can achieve but it all bodes well for the future.
To set the shot up I used my Nikon D800 in manual mode mounted on a tripod, the camera was set to f7.1, ISO 400, and on a two second exposure time. The shutter was released via a wired remote and not by the Nerotrigger. The Nerotrigger was placed just to the right of the poppers, out of shot but close enough to the popper to be able to pick up the noise of the 'pop'. The room I was shooting in had to be dark as it is the flash that captures and freezes the motion. The Nerotrigger was connected to my SB900 and this was set to manual mode on 1/32 power, I had a silver reflector to the left to bounce some of the light back.
At the beginning of the shoot I did encounter one problem and to be honest I was expecting it. When the Nerotrigger was placed on top of my camera, the noise of the shutter opening triggered the Nerotrigger to fire my flash, this was easily remedied by removing the Nerotrigger and placing it away from the camera.
I'll be using the sound trigger again this weekend to take some more adventurous shots, maybe a little like this one I took last week.

As indicated in yesterdays submission, I have again been playing with the Nerotrigger in sound mode, to say this little gadget is easy to use is an understatement. I am able to get consistent results and able to fine tune and tweak the timings to precise measurements. The Nerotrigger is rapidly becoming my 'go-to gadget'. The blurb for each image can be found with the image in my High Speed Photography gallery.
The next option to test I think will be the Timelapse function...............................or the laser trigger......................................but if there's a storm :-)
