80A Filter
This is a great color conversion filter used to compensate for the yellowish color tints we get indoors, with daylight films. This filter is for the use of daylight type color films with an artificial light source. 80A increases the color temperature from 3200°K to 5500°K for the use with 3200°K lamps (English translation: Use an 80A filter whenever using daylight color films indoors, under tungsten lighting - tungsten lights are the regular household incandescent bulbs most of us use in our homes). It compensates for the heavy yellow cast this kind of lighting causes when using daylight color films inside. Should be in every photographer's camera bag!
Using the 80A Filter
These pictures were taken on
daylight film, indoors, under tungsten
lights.
Illumination is tungsten light from the lamp. As you can see,
the uncorrected image on the left is too yellow. An 80A filter
was used to color correct the image on the right. When using
print film, this type of lighting problem can often be corrected
during the printing process, but with slide film, using the 80A
filter is a must.
80B Filter
This is a color conversion filter used to increase the color temperature. English translation: use an 80B whenever using daylight color films under photoflood lighting. Since daylight color films are balanced for lighting in the area of 5500K, and photoflood lights put out light at 3400K, this filter will increase the 3400K photoflood light to 5500K, so your pictures will look good.
80C Filter
This is a color conversion filter
used to increase the color temperature. English translation: use an 80C whenever using daylight color films
with clear flashbulbs. Since daylight color films are balanced
for lighting in the area of 5500K, and clear flashbulbs put out
light at 3800K, this filter will increase the 3800K photoflood
light to 5500K, so your pictures will look good.
81A Filter
This is a great light balancing filter used to decrease the color temperature slightly for a warmer (redder) tone. English translation: Use an 81A whenever using daylight color films on a cloudy, rainy, or heavily overcast day. It compensates for the heavy blue cast this kind of weather causes when using daylight color films. Should be in every photographer's camera bag!
81B Filter
This is a light balancing filter
used to decrease the color temperature slightly for a warmer
(redder) tone. They correct the tendency toward bluish tones.
Should be in every photographer's camera bag!
82A Filter
This is a great a light balancing
filter that all photographers need. It's used to decrease the
color temperature just a little bit. You use an 82A filter when
using daylight color films (which 90% of us shoot with 90% of
the time)in the early mornings or early evening sunlight. This
makes those heavily-tinted shots a little more realistic! Try
this out and see how much it improves the looks of your early/late
pictures.
85A Filter
The 85 series are color conversion filters for the use of tungsten type color films in daylight. 85 decreases the color temperature from 5500°K (outdoors daylight) to 3400°K for the use of Type A color films. English translation: When using Tungsten films under photoflood lights, use the 85A filter.
85B Filter
The 85B decreases the color
temperature from 5500°K to 3200°K for the use of Type B color films. English translation: When using Tungsten films outdoors in
daylight, use the 85B filter. The effect obtained is the same
as with daylight type color films used in daylight, without the
color shifts which would affect your pictures if you didn't use
these filters (so that's why the pros pictures look better than
ours!).
