long exposures
using a slow shutter speed to create a long exposure enables you to record something that the eye can’t normally see, rendering movement as a blur to add an artistic quality to your shots – such as clouds moving in the sky. Bulb mode puts the control of the exposure time in your hands, enabling you to set exposures longer than 30 secs. Some EOS cameras have a dedicated Bulb option (B). If yours doesn’t, select Manual mode (M) and scroll through the shutter speeds until ‘bulb’ appears.
