The Tiffen 4 x 5.65" 3 Coral Soft-Edge Graduated Filter helps
to specifically add a warm, pale orange coloration to skies and other
bright areas of an image while allowing a portion of the image to remain
neutrally colored. The filter's coloring is densest at the edge and
tapers to clear by the middle, with a soft-edged transition between the
density and clear areas. The 2 color density provides less coral
coloration than the 3 density, but more than the 1 density filter.
This filter is made using ColorCore technology, a process that involves
laminating the filter substrate between 2 pieces of optical glass and
grinding flat to a tolerance of 1/10,000th of an inch. It measures 4 x
5.65" / 101.6 x 143.5mm.
Note: A vertical orientation filter's line of transition runs parallel to the short side of the filter.
- Provides a natural-looking warming effect to select areas of the image.
- Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.
Coral Filters
As the sun moves through the sky,
the color temperature of its light changes.
It is often necessary to compensate for this in a variety of small steps
as the day progresses, to match the appearance of different adjacent sequences
to look as if they all took place at the same time. Coral
filters are a range of graded filters of a color similar to an 85 conversion
filter. From light to heavy, any effect
from basic correction to warmer or cooler than "normal" is
possible. Corals can also compensate for
the overly cool blue effect of outdoor shade.
