Tiffen 6.6 x 6.6" Combination Light Balancing 81EF/ND 0.9 Glass Filter

Several filter combinations are so popular that they are produced as two filter effects in one. These include: Neutral Density or Polarizer plus 81 or 85 Wratten.

The 81 series filters are useful with daylight corrected film in cool light conditions. As letters advance, density and warmth increases.

Neutral Density 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.

Tiffen ND Filter Features
*Eliminates overly bright, washed-out images
*Balances exposure
*Controls depth-of-field
*Allows slower shutter speeds to produce blurred motion effects
