CAMERA FILTERS

by Paul Wheeler, Digital Cinematography

Camera filters are used to alter the temperature of lights, change an image, or enhance colors. The following filters can also be used with digital shooting situations:

Color-Compensating Filters (CC Filters):

Come in primary colors and are used in front of the camera lens to correct light.

Color-Correction Filters: Used to correct a daylight scene when shooting with tungsten-balanced film.

Skin-Tone Warmers: Filters that will warm up skin tones that would appear cold otherwise.

Sepia, Coral, and Others: Filters that lend a variety of tints to a scene.

Graduated Filters: Usually come in colored or neutral density filters. These filters are used to darken or color one area of a scene without affecting the rest of the scene.

Natural-Density Filters: Used to open up the aperture at which you will shoot the scene.

Low-Contrast Filters: Reduce the overall contrast in a scene.

Ultra-Contrast Filters: Like the low contrast filters, but work with the incident, ambient light. Ultra contrast filters work beautifully with bringing up shadow details.

Fog Filters: Try to emulate fog. Images will have less definition and contrast.

Double Fog Filters: Objects near to the camera will appear less affected than those far away.

Pro Mist Filters: Give a glow around intense sources of light. Highlights become “pearlized.”

Net Filters: Nets will affect the scene differently depending on the color used.

A white net will diffuse highlights into shadows. Dark nets will often bleed shadows into highlights. A brown net will add richness and overall warmth.

Enhancing Filters: Bring out one color at a time without affecting any of the others. These filters affect the red and orange portions of a scene.

Fluorescent-Light Correction: The FLB

filter corrects fluorescent light to type B film or tungsten-balanced video camera. The FLD filter corrects fluorescent light to daylight camera.

Polar Screens: Screens that are used to darken the blue portion of a sky in color photography as well as reducing reflections in parts of a scene.
