Neutral Density

.3, .6 , .9

Neutral Density filters reduce the amount of light passing through the camera lens without changing the color of the scene. Especially useful in bright light condi- tions to help prevent overexposure. Also allows 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.

❍Balances exposure.

❍Controls depth-of-field.

❍Allows slower shutter speeds to produce blurred motion effects.
