In photography and image processingcolor balance is the global adjustment of the intensities of the colors typically red, green, and blue primary colors. An important goal of this adjustment is to render specific colors — particularly neutral colors like white or grey — correctly. Hence, in color balance, the general method is sometimes called gray balanceneutral balanceor white balance.

No adjustment:. The colors of the RGB color model can be mixed to produce the cyan, magenta, and yellow of the CMY color model and vice versa. Two colors of one model are mixed to produce the color of the other mixing blue and green produces cyan, for example. The remaining color is the complement of the color produced red in this example. Complementary colors are: red and cyan, green and magenta, blue and yellow. Click Details

Careful color balance showcases colored light illuminating an iceberg in Ilulissat, Greenland. Color balance is a fundamental aspect of photography. My own, extensive exploration of color balance has deeply affected how I perceive and photograph the world around me. Let me share that knowledge, showcased with images from Greenland and China, to demonstrate how control over color balance will positively impact the success of your photos. Depending upon the desired outcome, either a neutral color balance or a more emotionally charged image will result. Recording colors as neutral as possible, without any color cast, is often considered important to achieving the desired result. White balance settings are adjusted, in camera, to allow you to achieve a neutral color balance in your photos. However, as is the case with sunset photos, many images benefit from the emotionally transforming color of light. From my own experience, photographing under the midnight sun does introduce some potential difficulties, one of which is achieving the most appropriate color balance. Greenland is a wild, remote and very beautiful country. And the landscapes of Greenland, particularly under the midnight sun, are absolutely epic. I spent around a week in Western Greenland, most of it in the tourist town of Ilulissat, on the edge of the fabulous Ilulissat Icefjord and Disko Bay. The above photo was made during an overnight hike I undertook around the town of Ilulissat from around 9pm till about 5am the following morning.

Conceptually, color balancing consists of two steps: first, determining the illuminant under which an image was captured; and second, scaling the components e. Color constancy is, in turn, related to chromatic adaptation. At best the appearance of the in color balance dress has shifted to a cool white, due to the bluish color of the sky that's being reflected into it.

You can change the color balance in the camera before taking a photo or in an editing program during post-processing. Color balance is an adjustment that affects the overall mixture of colors in a photograph. To balance an image, you simply adjust the intensities of the cyan, magenta, and yellow tones. The end goal of color balance is usually to achieve realistic and accurate colors. In many cases, photographers and image editors use color balance adjustments to remove a color cast — a tint that affects the entire photo. To correct it, you can reduce the intensity of the green hue. Since color balance is a global adjustment, this step affects all the colors in the photo. Done correctly, it removes the green cast and restores the natural colors. Color balance is almost always oriented around white, neutral, or gray tones.

In photography and image processing , color balance is the global adjustment of the intensities of the colors typically red, green, and blue primary colors. An important goal of this adjustment is to render specific colors — particularly neutral colors like white or grey — correctly. Hence, the general method is sometimes called gray balance , neutral balance , or white balance. Color balance changes the overall mixture of colors in an image and is used for color correction. Generalized versions of color balance are used to correct colors other than neutrals or to deliberately change them for effect. White balance is one of the most common kinds of balancing, and is when colors are adjusted to make a white object such as a piece of paper or a wall appear white and not a shade of any other colour. Image data acquired by sensors — either film or electronic image sensors — must be transformed from the acquired values to new values that are appropriate for color reproduction or display. Several aspects of the acquisition and display process make such color correction essential — including that the acquisition sensors do not match the sensors in the human eye, that the properties of the display medium must be accounted for, and that the ambient viewing conditions of the acquisition differ from the display viewing conditions. The color balance operations in popular image editing applications usually operate directly on the red, green, and blue channel pixel values, [1] [2] without respect to any color sensing or reproduction model.

The inclusion of foreground subject matter allowed me to emphasize contrast between the following compositional elements within the scene: Light and dark Smooth and textured Warm and cool colors Likewise, the little patches of green grass in the rocky foreground contrast nicely with the soft pink colors in the distant ice and sky. If the primary subject of your image is a portrait then it's important to consider whether it's appropriate to be warming up the color of the light with a Cloudy or Shade white balance as that may result in overly warm skin reproduction.

There are others who prefer to trust their camera knowing that they can tweak the results on the desktop. This approach should stop your camera, not knowing it's a sunset or that you're wanting to record the color of those neon lights, from trying to neutralize the color of the light. In that case set your camera to the even stronger Shade white balance setting. Under certain circumstances the Cloudy white balance still won't neutralize all of the bluish light.
