Having tried many forms of high speed flash in the past, including building trigger systems using light beams, microphones and motion sensors to trigger flashes. Digital brings a whole new dimension as the results can be reviewed instantly. In the good old days of film, testing trigger systems required extensive notes and waiting for the film to be developed to know the real results. Resorting to large format cameras with a polaroid back was the closest to digital but far more expensive?

After researching many systems on offer on the web I considered building my own with support from a great wesite Hiviz.com but after much deliberation decided on a prebuilt unit called a "Stopshot" from cognysis.

I have already had great fun experimenting with waterdrops and will be trying to capture high speed sports shots in the coming months.

I am already wondering if there are ghosts in waterdrrops!
