Whilst doing some paint explosions, firing it off a speaker to make it jump over the Christmas period, I also experimented with adding glitter to the speaker.
This also works well firing it off the speaker. Here are a few of the resulting images.
I also tried some combinations of the glitter with paint on the speaker.
These are two of them.
These images shot using Stop Shot, a speaker with a black ballon on it. Canon 760D with 100mm Canon Macro lens, and 2 580ex speedlight flashes triggered by the stopshot ( microphone triggered ).
