Understanding White Balance for Photography and Videography
WHAT IN THE WORLD IS WHITEBALANCE & WHY DOES IT MATTER?@campbellcamerasVS
SEE THINGS DIFFERENTY@campbellcameras1DSLRS and Video Cameras do not see the same waythat the human eye doesOur eyes can adjust the colors of what weare looking at by the light. Cameras try, andsometimes succeed in producing the rightcolor in AWB (auto white balance) but mostof the times they FAIL.

White Balance Settings5@campbellcamerasThese are your typical white balance options on most camerasIncandescent setting is best for traditional household bulbs.Fluorescent will prevent the green cast common to photos taken in fluorescentlight.Cloudy will add a bit of warmth to the light.Flash adds a more aggress touch of warmth to take the edge off the birght light of aflash.Shade adds a slight pink tone to eliminate the blue cast that shadows take.Sunny/ daylight sets the color temperature to around 5000k, which is your typicalmid-day sunIn Auto setting the camera will read the scene’s color temperature (basically the hue and intensity of a particular lightsource, measured in degrees Kelvin) and choose a setting from its collection of pre-programmed adjustments.Custom Temperature is a do-it-yourself choice, in which you actually set the degrees Kelvin to affect how thecamera will see and render the hue and intensity of colors in the scene. Using the Kelvin setting you can fine tunethose colors to your definition of “accurate,” or skew the colors to reflect your choice of the scene’s mood and feeling.Custom White Balance - With that option selected, hold a white card or pure white object in front of the lens andpress the shutter button. The camera will read and lock in the color temperature of the light reflected from that card,and that locked-in reading now becomes the standard for the camera’s white balance setting. Custom WB is an idealway to handle a scene that presents mixed lighting—fluorescent lights in the ceiling and daylight streaming through awindow, for example—because it takes into account all the lighting in the scene.
How To Set Custom WB5@campbellcamerasHave a White Card, computerpaper, or anything pure white.1 Go to your WB settings in yourcamera and select Custom WB2The usual symbolPlace the white object in your shotand have it cover the entire framein your camera. When you pressthe shutter button it locks the WB.3
