Long exposure times permit the camera to gather enough light to take a quality photo, even in the darkest of
environments. If you want to keep the noise levels low and use lower ISO levels in dark environments long exposure
times can be very useful. Most people don't normally need to take very long exposure photos, but they can provide
an amazing creative opportunity for those interested. For example you can take long exposure shots of the night sky
to capture the movement of stars across the sky, capture nigh-time vistas, landscapes at dusk, turn water in to
flowing clouds, and add blur to photos for effect.
Get Creative with Long Exposures
The following photos demonstrate how long exposure time can create photos that would otherwise be
impossible.
Nighttime Landscape

shows a great late night landscape. The longer exposure clips out and blends the lights and smooths the water and
sky leaving the landscape in crisp detail. Shot on a
Canon XSi entry-level
dSLR
Flowing Water Effect

This photo by

Photography illustrate a 4s long exposure of a waterfall via a
Canon EOS 400D a f/16 18mm. The long exposure turns
the waterfall and water into pillowing clouds creating a wonderful calming interpretation.
Nighttime Snow
Paulo
Brandao's great nighttime shot uses a super long 124 second exposure using a
Nikon D90, the effect is a wonderfully dark
interpretation of the trees and snow at night with rays of light bursting through from the house beyond. Shot at
18mm f10 ISO 100.
Nighttime Highway Scene

This photo by
nrbelex via flickr shows
a fantastic interpretation of a nighttime highway - using a long exposure to turn the taillights in to bands of
light trailing up the photo to the horizon. Shot with a
Canon XTi.
