Tiffen 4X5.650 NEUTRAL DENSITY 0.1
Neutral Density Filters
These filters reduce the amount of light passing through the camera lens without changing the color of the scene. They are especially useful in bright light conditions to help prevent overexposure. Neutral Density filters also allow proper exposure at a wider lens opening for reduced depth-of-field to highlight a key subject by making the foreground and/or background out of focus.
Eliminates overly bright, washed-out images
Allows slower shutter speeds to produce blurred motion effects
