The challenge for week 7 of my 52 week Landscape Composition Photo Challenge is Long Exposure. The goal for this week was to slow down the shutter speed, significantly. When you hear Long Exposure, one of the first things that come to mind is a waterscape where the waves have been smoothed while keeping some element in the frame sharp like foreground rock or bridge. However, Long Exposure can basically be anything. As long as you slow down your shutter speed to show motion, it’s considered long exposure. There is no clear definition of what Long Exposure is.
Long Exposure Photography portrays time; at least, that’s the intent. Moving clouds or waves or light trails or even star rails all portray time or passing of time in your photos. For a photo to be considered long exposure, you don’t necessarily have to use a certain shutter speed. As long as your intention is to capture moving objects with a shutter speed and exposure time longer than ‘necessary’, then it qualifies as Long Exposure. Some people use Long Exposure in a busy street to blur people and create a ghostlike feel. Some people take it a step further. If they are in a busy monument or natural attraction and they don’t want people in their photo, they use a ultra-long exposure and anyone that does not stay stationary for a long time disappear from the photo.
Here’s an example of Long Exposure that I shot for this week’s challenge. This is a shot of the Bay Bridge and San Francisco Skyline shot from Treasure Island. This was well past Sunset and my goal was to use a Long Exposure (about 2 minutes) to capture all the lights from the Bay Bridge as well as the Skyline. Not what you think when you hear Long Exposure but definitely fits the bill for this week’s challenge.
