Ironically, white balance makes a great impact on colors in the footage you record. Always check white balance settings before shooting, as adjusting it in post-production would be cumbersome.
When preparing a shot, match the color temperature setting on your camera to the type of lighting being used. White balancing (WB) means to set the proper color of white.
Color temperature describes the color characteristics of light when heated to a specific temperature, measured in Kelvin (K). Temperatures can range from warm (yellows) to cool (blues).
Cover the bases
To get the color temperature right, most video cameras have presets for shooting under tungsten light (3200K) or daylight (5600K). Auto WB and manual WB controls are also common fixtures.
When shooting under mixed light, adjust lighting first using gels. Set your lamps to daylight or tungsten depending on the majority of lights being used to easily match it with a WB preset.
Shine it white
When WB presets are not available, set the camera’s WB up with a lit white card in the scene. Point the camera at the card and use the auto WB button to set the white point. Make sure most of the card fits in the camera’s viewfinder.
To play with temperature settings in your video, make it warmer or cooler-toned with color-balancing cards. Manual adjustments to the color temperature setting on the camera can also give the same effect.
For manual white balancing on DSLRs, capture an image of a white card or surface and assign the photo as the source of ‘white’ in the WB menu.
Black balance (BB) switches on cameras can help reset the black point. Cover the lens fully to press the BB control so the camera understands how dark black is. If BB is not serviced, some cameras can drift to produce discoloration or strange tints in dark areas.
