Stock Shot Project

For this shot we wanted the over all scene to be sharp but the person in the background to blur as he walked by. To accomplish this I needed a slow shutter speed of 1/8-1/15sec to create the blur in the person walking.  Our studio is lit by daylight so I used a neutral density filter to reduce the exposure, and then asked the foreground model at the computer to hold still.  Shot with a Nikon D3s camera on a tripod and 78mm on a Nikon 70-200mm zoom with f/2.8 aperture.
