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!

London Evening – 01

A couple of days before the New Year Daphne and I went for one of our favourite walks – along the South Bank of the River Thames, between St Pauls Cathedral and Embankment Station. These are some of the images I caught along the way.

All taken on the Olympus EM-1 Mk II ( I hear there’s a new one coming out later this month. Oh dear!! ) … and a 12-100mm f4 Pro Lens, handheld. ( Yes, I know!! )

FIDDLEHEADS

Taken in Blake’s Wood near Danbury in Essex, the visit was initially to take shots of the bluebells ( for which Blake’s Wood is renowned ) – but I came across these Fiddleheads : developing ferns – before they have unfurled into the adult plant we are more used to.
