Stroboscopic Flash – 06

A new experience this week – I’ve had a go at Stroboscopic Flash. Impressive name, difficult technique. With a bit of a learning curve to climb!

Stroboscopic Flash – a single, longish exposure ( perhaps 2 or 3 seconds ), where the subject is moving in the frame and the strobe/flash light goes off a number of times whilst the shutter remains open. Best executed in as dark a room as you can manage with a plain black background set up as far back from the subject as possible. ( You may want to keep a low-level light on to stop you tripping over tripods and light stands, etc – but if the light is too bright and the exposure very long, that light will show in the final image ).

You’ll need a strobe that will fire a set number of times at a set frequency ( numbers such as 4Hz are oft quoted, meaning 4 flashes in 1 second ).

So 8 flashes at 4 Hz will require an shutter speed of 2 seconds ( to accommodate all 8 flashes ).

I set the Olympus to Manual mode, 1/250 sec and an f stop determined by trial and error. I told you I was learning! And I used a wireless remote to trigger the strobe.

These images are not perfect, I know that, but they demonstrate the principle and give me a base from which to improve.

If you try it, have fun. And be prepared to take LOADS of images to catch the ones that work!
