User manual for the Tiffen 138mm WW IR Polarizer Filter W138IRPOLA
The user manual for the Tiffen 138mm WW IR Polarizer Filter W138IRPOLA provides
necessary instructions for the proper use of the product Photography - Filters - IR Control.
The Tiffen 138mm WW IR Polarizer Filter is a combination linear polarizer and near-infrared to infrared control filter that is designed for digital cinematography. When this filter is used, it helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. Simultaneously, near-infrared light waves beginning at 680nm are blocked by approximately 80% and infrared light waves at higher frequencies are further impeded until nearly flat attenuation is achieved at 720nm.
This filter is useful as many digital motion-picture cameras are designed to maximize their ability to capture red hues, and in that process near-infrared or infrared contamination may occur. If the proportion of near-infrared or infrared light that reaches the sensor of a digital cinematography camera becomes too great, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.
While helping to preserve color accuracy when using a digital motion-picture camera, the Tiffen 138mm WW IR Polarizer Filter also addresses the effect of light from the sun becoming partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
A linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarize linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, in-camera auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
This filter is recommended when not using in-camera exposure metering or autofocus. It is non-coated with a 3x filter factor that results in a 1.6 stop exposure reduction. Constructed from Water White optical glass, the Tiffen 138mm WW IR Polarizer Filter is 138mm in diameter and mounted for use in third-party or custom filter holders. It is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. No front or rear threads are included on this filter's ring, or mount.

The user manual for the Tiffen 138mm WW IR Polarizer Filter W138IRPOLA can be downloaded in .pdf
format if it did not come with your new ir control, although the seller is
required to supply one. It is also quite common that customers throw out
the user manual with the box, or put the CD away somewhere and then can’t find it.
That’s why we and other Tiffen users keep a unique electronic library
for Tiffen ir controls,
where you can use our link to download the user manual for the Tiffen 138mm WW IR Polarizer Filter W138IRPOLA.
The user manual lists all of the functions of the Tiffen 138mm WW IR Polarizer Filter W138IRPOLA,
all the basic and advanced features and tells you how to use the ir control.
The manual also provides troubleshooting for common problems. Even greater
detail is provided by the service manual, which is not typically shipped with the product,
but which can often be downloaded from Tiffen service.
If you want to help expand our database, you can upload a link to this website
to download a user manual or service manual, ideally in .pdf format. These pages
are created by you – users of the Tiffen 138mm WW IR Polarizer Filter W138IRPOLA. User manuals are also
available on the Tiffen website under Photography - Filters - IR Control.
