Tiffen Solid Neutral Density Filters
Tiffen ND 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
A fixed ND are measured in increments of Stops. An illustrative chart can be found below.
OPTICAL DENSITY | F-STOP REDUCTION | |
---|---|---|
ND3 | 0.3 | 1 STOPS |
ND6 | 0.6 | 2 STOPS |
ND9 | 0.9 | 3 STOPS |
ND12 | 1.2 | 4 STOPS |
And so on.
Tiffen Graduated (Grad) ND's
Graduated Neutral Density (Grad) filters, also known as "grads", are a tool that can help balance the contrast between a bright sky and the darker ground below. They are particularly useful for capturing scenes with a wide dynamic range, such as sunrises and sunsets.
Here are some benefits of using Grad filters:
Tiffen IRND's
When you want to either use or cut IR light from entering your image, Tiffen’s IR Control filters include individual Hot Mirrors, Full Spectrum IRND’s that cut Far Red, Near IR and a combination of Hot Mirror and Full Spectrum IRND that cut all Far Red and IR wavelengths. We also produce visible wavelength blockers as with the 87 filter which allows only IR through.
An IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination.
When using a standard neutral density filter to counter the increased light sensitivity afforded by the HD sensor, the effects of infrared pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter.
