Long Exposure Photography
Long exposure photography involves using slow shutter speeds to capture moving elements within an image. It helps to have a stationary object within the frame to complement this effect. To achieve this a tripod is necessary. If using a DSLR consider using the mirror lock up function and a wireless or wired shutter release cable to eliminate any camera shake. The image to the right was shot at night using a 10 stop neutral density filter since the moon was fairly bright behind the thin cloud layer in the sky. The camera was set to ISO of 200, manual focus, and camera manual mode used. I set the aperture to f16 for a large depth of field and also to cut down the amount of light entering the camera for a longer exposure. I took a few test shots using different shutter speeds until I was happy with the final exposure. The final image was obtained using a 30 second exposure. This shutter speed was long enough to capture movement in the clouds and water for a soft, surreal effect I was trying to achieve. In post processing, it was converted to black and white and slight adjustments to contrast was made. Noise can be an issue when shooting long exposures and some noise reduction was implemented in post processing as well.
