Things You'll Need
Instructions
Place the neutral density filter on your camera. In most cases, the filter will simply screw onto the front of your camera lens. On more elaborate setups, you may have to slide a filter adapter over the front end of the camera and then screw or slide the filter into the adapter. The filter will help block light which will allow you to use a necessary slower shutter speed.
Set your camera to manual mode. On most SLRs you can do this by rotating a dial on top of the camera. Manual mode is often represented by an "M."
Change the aperture to the desired size. The smaller the aperture the more the background will be thrown out of focus, but more light will pass through the lens. Using an aperture of f/11 is a good starting point.
Set the shutter speed on your camera by rotating the dial on the top of your camera. Use a shutter speed that is slower than you would normally use. For faster moving objects such as a car, start with a shutter speed of 1/90. If you are photographing a slower object such as a person walking, start with a speed of 1/30 or lower.
Frame your subject in the viewfinder of your camera. Manually focus the lens by rotating the lens until the subject isn't blurry.
Move your camera with your subject so that the subject appears to stay in one spot when looking through the viewfinder of your camera. At the desired moment, press the shutter release button to take the photograph.
