Daytime long exposure at Baker Beach

High neutral density filters allow for very very very long exposure times, even in broad daylight!! The filter I used here, an ND 3 (10 stops) lets through only about one thousandth of the light, that is 0.1%!! Hence I was able to shoot the San Francisco Golden Gate from Baker Beach at 3pm in the afternoon and get a 25 second exposure!

Check out my latest Physics & Photography post to read about what type of photographs I like to take using neutral density filters and the physics behind the large colour cast of very opaque high ND filters.
