The Schneider 85 series will produce natural colors when shooting with tungsten film outdoors.
What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series of filters will "bring back", i.e. color balance the tones in your images. These yellow filters are used to correct differences in color temperature between the recording medium (film/video) and the light source.
It should be noted that an 85 filter produces slightly cooler results than an 85B (with tungsten film in daylight) whereas an 85B converts tungsten film to daylight. The 85C produces the coolest results - more than either the 85 or 85B. However, it is interesting to remember that an 85C is also useful as a creative warming filter with daylight film in daylight.
Circular Polarizer 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.
Note: Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters when using daylight film under tungsten lighting. Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems).
Combination 85/Circular Polarizing
Polarizer = Between 2.3 and 2.8 (approx. +1.3 stops)
85 = 1.8 (+2/3 stop)
85 = Removes excessive blue from images and produces more natural colors
Polarizer = Removes reflections and increases color saturation without affecting the overall color balance
85 = When pleasing color balance is desired when shooting with tungsten film outdoors
Polarizer = Nature, travel, outdoor photography
85 = Decreases the color temperature from 5500-3400 degrees Kelvin
