Tiffen 72mm Neutral Density 0.3 Filter

The Tiffen 72mm Neutral Density 0.3 Filter is designed to reduce the amount of light passing through the camera lens without changing the colours of the scene. They are often used in bright conditions when capturing landscapes or using long exposures to capture blurred motion effects. This ND 0.3 filter reduces the light by one f-stop.

Tiffen Neutral Density Filter

• Eliminates overly bright, washed-out images
• Balances exposure
• Controls depth-of-field
• Allows slower shutter speeds to produce blurred motion effects

About Neutral Density Filters

When it is desirable to maintain a particular lens opening for sharpness or depth-of-field purposes, or simply to obtain proper exposure when confronted with too much light intensity, use a neutral density (ND) filter. This will absorb light evenly throughout the visible spectrum, effectively altering exposure without requiring a change in lens opening and without introducing a color shift. Neutral density filters are denoted by (Optical) Density value. Density is defined as the log, to base 10, of the Opacitance. Opacitance (degree of absorption) of a filter is the reciprocal of (and inversely proportional to) its Transmittance. As an example, a filter with a compensation of one stop has a Transmittance of 50%, or 0.5 times the original light intensity. The reciprocal of the Transmittance, 0.5, is 2. The log, base 10, of 2 is approximately 0.3, which is the nominal density value. The benefit of using density values is that they can be added when combined. Thus two ND .3 filters have a density value of 0.6. However, their combined transmittance would be found by multiplying 0.5 x 0.5 = 0.25, or 25% of the original light intensity. - Nat Tiffen

• Tiffen Neutral Density filters reduce the amount of light passing through the camera lens without changing the colour of the scene
• Especially useful in bright light conditions to help prevent overexposure and achieve a balanced exposure
• Allows specified exposure when desiring to expose at large apertures despite being present in bright lighting conditions, which normally require small shooting apertures
• Neutral Density filters allow aperture control for selective depth of field shooting
