Effect |
| Skylight |
Used to eliminate blue cast in distant scenes and in open shade because it absorbs ultraviolet rays and some blue
light. It also clears up environmental haze a little.
|
| UV |
(a.k.a. UV Haze) Used to eliminate blue cast in distant scenes and in open shade. Absorbs ultraviolet rays. It
also clears up environmental haze a little.
|
| FL-D |
Eliminates green cast when daylight type films are used under fluorescent lights. |
| ND |
Used to lower intensity of light striking the film to enable larger apertures for shallow depth-of-field, slower
speeds and special effects. Of ten come in .3, .6 & .9 densities. (1/3, 1/6, 1/9 f-stops). |

Now use daylight color films with 3400°K photofloods. |
| 80C |
Now use daylight color films with 3800°K lamps. |
|
|
Filters designated with 81 filters are a little bit warm in Kelvin Temperature
|
| 81A |
Now use tungsten "Type A" tungsten (movie film) with 3200°K photofloods. |
| 81B |
Eliminates blue cast found in high altitude mountain photography or when shooting during a very clear day. |
| 81C |
Helps counter the blue cast in cloudy and rainy weather. |
