Polarizer Tips
LINEAR (SR)
Produces deeper colored blue skies, which at the same time creates a striking contrast with white clouds. Minimizes light reflections from glass and water Reduces glare from non-metallic surfaces. Provides a general color saturation to both cool and warm tones. Can be used in extremely bright light situations to reduce the amount of light entering the camera; this enables more selective depth of field control. Manufactured in self-rotating and drop-in formats. Note: using a Linear Polarizer on an auto focus camera with a beam-splitting meter will result in under-exposure of approximately 2-3 f:stops. Light is polarized by both the filter and the beam-splitting meter which results in double polarization. However, Linear Polarizers can be used with both non-auto focus and auto focus video cameras.
Light Loss: 2 f:stops
CIRCULAR POLARIZER
Provides the same filter effects as a Linear Polarizer, but is designed to work with auto focus cameras with beam splitting metering. The Circular Polarizer has linear polarizer construction plus a built-in "Wave Retardant" to ensure proper exposure. The linear element polarizes the light, and the wave retardant de-polarizes it, and then the beam-splitting meter polarizes the light again for proper exposure. The use of a Linear Polarizer with a beam-splitting meter will result in underexposure. Also used in video for video assist. (video tap).
Light Loss: 2 f:stops
ULTRA POLARIZER
Tiffen's most advanced polarizer. Provides a much greater effect than a standard linear polarizer. Causes deeper saturated colors, deeper blue skies, and a greater reduction of reflections. Available in Ultra Linear and Ultra Circular Polarizers.
Light Loss: 2 f:stops
WARM POLARIZER
Combines a polarizer and the exclusive Tiffen Warm 812 filter. Has all the polarizer effects along with those of the 812: warms the scene, eliminates excess blue caused by electronic flash, video lights, and shooting in outdoor open shade. Available in Warm Linear, Warm Ultra Linear, and Warm Ultra Circular Polarizer.
Light Loss: 2 f:stops
85 POLARIZER
Combines a Linear Polarizer and an 85 Color Conversion filter. Converts Type A film to daylight and adds a polarizing effect. Available in rotating and non-rotating mounts. Also available in 85 Ultra Linear Polarizer and 85 Ultra Circular Polarizer in non-rotating mounts.
Light Loss: 2 2/3 f:stop
POLARIZER TIPS
TIP #1: How much a polarizer filter will darken a sky depends on the type of sky and your shooting angle in relation to the sun.
TIP #2: On a sunny day, position your shoulder towards the sun and your subject at a right angle to your shoulder. When the sun is high in the sky, maximum polarization will result along the horizon. When the sun is low in the sky, maximum polarization will result in all areas in front of and behind you.
TIP #3: A polarizer has very little effect when used under a gray, overcast sky.
TIP #4: Remove any protective lens filters when using a polarizer.
TIP #5: Use a polarizing filter indoors only for reducing relections and glare. Any color saturation will be minimal. Remember, a polarizer filter will effectively reduce your lens aperture by up to 2 f:stops.
TIP #6: Combine an Ultra Polarizer and an 812 filter to obtain "Warm Polarizing" effects.
TIP #7: Combine a polarizer with a Tiffen Enhancing filter for dramatic color saturation. The Enhancing filter provides deep saturation of warm tones, much greater than that achieved by a polarizer or a Warm 812 by themselves.
TIP #8: Use a polarizer filter to control depth of field. This is similar to using a Neutral Density filter, except that the Neutral Density will render "neutral" colors, while the polarizer saturates colors. Neutral Density filters are available in greater light reducing densities than polarizers.
TIP #9: To distinguish a Circular Polarizer from a Linear Polarizer, turn the filter backwards and look through it into a mirror. If the filter image in the mirror is black, you have a circular polarizer. If the image is clear, you have a linear polarizer.
