shutter speed

With the excitement of the new Eastern span of the Bay Bridge, I took the opportunity to work on low light photography.

According to wiki... "In photography, shutter speed or exposure time is the length of time a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time."

In the first photo above, I set the shutter speed to .0125 (1/80) seconds.  In the second photo, shutter speed was at 0.02 (1/50) seconds with all other settings remaining the same.  In the last photo, the shutter speed was set at 0.1 (1/10) seconds, again with all other settings remaining constant.  Notice that with a longer shutter speed, the camera was able to pick up much more light.  We can now even see a part of the old Bay Bridge.

On average, we could hold the camera steadily without support for about 0.01 (1/100) second.  With the longer shutter speed in the shots above, I rested the camera on a still object to capture the photo.

More photos of the bridge to come... till next time!
