At right is a photo I took at Seal Beach Pier. It's a 40 second daytime exposure taken on a very bright day.
You'll need to purchase a neutral density filter, and it will set you back a few bucks. A neutral density filter will allow you to shoot at long shutter speeds in the daylight. By doing so, it will blur motion. Uses include landscape photography with ocean waves and/or moving clouds.
Hope you enjoy.
