In this article, we will delve into the world of long exposure photography, exploring its techniques, equipment requirements, and creative possibilities.
Understanding Long Exposure
What is long exposure?
Long exposure refers to the technique of using a slow shutter speed to capture an image over an extended period. In traditional photography, the shutter opens and closes quickly, capturing a freeze-frame of a moment.
However, in long exposure photography, the shutter remains open for a longer duration, allowing light to accumulate on the camera’s sensor.
How does it work?
When the shutter is open for an extended time, any movement within the frame will create motion blur. This effect is particularly evident when capturing subjects in motion, such as flowing water, moving clouds, or vehicles on a busy street.
By intentionally introducing motion blur, long exposure photography can transform ordinary scenes into extraordinary works of art.
