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
* Balances exposure
* Controls depth-of-field
* Allows slower shutter speeds to produce blurred motion effects
Neutral density (ND) filters have many applications. They are best for making adjustments in excessive light situations, especially when they cannot be handled in any other way. The filters? usefulness is based on their ability to absorb light evenly throughout the visible spectrum. That?s what makes them "neutral." They are not supposed to produce a color bias. Tiffen ND filters always have been designed to function similarly to the traditional industry standard, the Kodak Wratten gel filters. Decades of successful production use are evidence that they produce photographically neutral results. Even so, when a leading dealer came to us with his own test slides, we felt that they were of sufficient interest to share them with you, our customers. First a little background as to their source. Although the dealer requested that we maintain their anonymity, they are, in fact, one of our worldwide dealers and they represent the other filter manufacturers in the test. All of the tested filters were pulled from their own stock, without any special selection process.
