The Tiffen Enhancing/Ultra Linear Polarizing Glass Filter is a wonderful filter designed to bring significantly more "snap" to your images.
Ultra Polarizer
If a traditional polarizer doesn't give you enough "zip", the "Ultra" polarizer gives you a little more. It will bump up your blue skies even more - making the difference between a good photo and a great image.
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
Enhancer
The Tiffen Enhancing filter is a combination of rare earth elements in glass. It removes a portion of the spectrum in the orange region, increasing the color saturation of reddish objects by eliminating the muddy tones and maximizing the red hues with minimal effect on other colors.
We all love Autumn. When the leaves begin to change color, we're all left breathless by their eternal beauty. Capturing those stunning colors on film or digital becomes a priority for any avid photographer. The Enhancing filter is a most valuable tool when it comes to this kind of nature photography. An Enhancer increases the saturation of the red/orange end of the spectrum and makes earth tones thoroughly saturated and vibrant. Colors appear to "pop".
You will find that the Enhancing filter works best in early morning or later afternoon photography - when the light is intense rather than the semi-washed out illumination of mid-day. This filter is also optimized for use during the overcast days of Autumn. Try it on an old barn or wooden bridge.
Tiffen makes the Enhancing filter in many sizes to accommodate the many uses this filter has. This filter can be used by the pro and amateur alike, weekend photo warrior or pro cinematographer and must be considered an essential addition to any photo arsenal.
