WHAT YOU ’LL NEED
Many scenes contain movement, and by choosing the right shutter speed you can control which elements of the picture are blurred. The techniques for doing this are relatively straightforward, but you will need the right equipment.
You’ll need a tripod to keep the camera still during the long exposures required for these shots – the heavier the better, to cut vibrations.
There’s too much light in the daytime for long exposures, so you’ll need an ND (neutral density) filter to reduce it and allow long exposures.
A remote release will prevent you jogging the camera when you fire the shutter. Some have timers for long exposures.
