Marshall Point  Marshall point light is located near the fishing village of Port Clyde, Maine.  You may recognize it from the movie " Forest Gump" starring Tom Hanks, where the long boardwalk was used as the termination point for Forest's long run.  Weather and lighting conditions were excellent for seascape photography that evening, however, I wanted to achieve a very silky water look in this image.   I was unable to use a long shutter speed to achieve that look due to the lighting conditions. I added a dark filter (6 stops) to reduce the light level and allow me to set the camera for a thirty second exposure.  Getting a good quality filter is important to retain good color and sharpness.  

The image was taken with a Pentax K3 (24mpix) camera and 18-70 F4 lens , f14, for 30 seconds
