The Tiffen 58mm 85C Color Conversion Filter helps to decrease
the color temperature from 5500 to 3800K, allowing the use of
tungsten-balanced film in daylight conditions. The warming effect of
this filter requires a 0.3-stop increase in exposure for normal results.
This filter 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.
Color Conversion Filters
Sunlight, daylight, incandescent, fluorescent, and other artificial
light sources all have color characteristics that vary significantly.
Filters give you better images by adjusting for these light variations.
Film and video are rated for a particular color temperature such as
that of daylight or tungsten light. Filters are used to correct
differences in color temperature between the recording medium and the
light source.
85 Series
Using tungsten film in daylight will produce a bluish cast. The 85
Series will produce natural colors when shooting with tungsten film
outdoors. For best results use the filter that most accurately matches
your film type.
85
- Produces slightly cooler results than the 85B
85B
- Converts tungsten film to daylight
85C
- Useful as creative warming effect with daylight film in daylight
- Designed to produce cooler results with tungsten film in daylight than the 85 or 85B
