Landscape photography is a genre where long exposures can be a good thing. They let you get motion into a photo, in the form of blurred water, clouds, grass, and leaves on trees.

Surely you’ve seen a photo like this before—a night view of a big road in the city, full of light trails from passing cars. It looks like a very long exposure was used. But was it? There’s an alternative approach you can take that gives better control over the results.
