With a recent addition of a neutral density filter, I decided to go over to Roseville central park and see if I couldn’t get some nice blurred water. For those who don’t know, a neutral density filter basically darkens the picture. So, this means less light goes into the lens and you need to take longer shutter speeds to get a picture. With a tripod (of course), this is a 1 second exposure of the water.
Why can’t I do this without this filter? Well, if I set my camera to take a 1 second exposure without this lens, in daylight, the picture would be all light and washed out (because all that bright light would be hitting the sensor for a full second). The ND filter, by reducing the light that comes into the camera, lets you take a longer exposure.
I then converted this to black and white. Here’s the result:
