Longtime Exposure
Technique - Technique

Motion Blurring

Usually we try to avoid motion blurring but when used to the extreme (with long time exposure) the resulting pictures are often great. Just have a look at the image below. It was exposed with about 20 seconds so the cars on the highway transform to lines of light.
 

Bridalveil

The "Bridalveil" effect is typically used with waterfalls. It's finally nothing else than a simple long-time exposure so you need a tripod here. The effect starts to get obvious with exposure from 1/2 second and up. The surrounding environment remains the same while the falling water produces stripes of bright light on the film. The longer you expose the more enhanced is the Bridalveil. The optimal exposure time is also dependent on the height of the waterfall but I would suggest about 4-8secs as a rough rule.
 

Zoom Blurring

This effect is achieved by choosing a relatively long exposure time and zooming just after the shutter is released. The picture below shows a sort of coma effect because the zooming was finished well before the shutter was closed. There numerous variations possible here.
