Fehéregyensúly, which translates to "white balance" in English, is a crucial setting in digital photography and videography that ensures the colors in an image appear natural and true to life. When a camera captures an image, it records the color of the light source illuminating the scene. Different light sources, such as daylight, incandescent bulbs, or fluorescent lights, emit light with varying color temperatures, meaning they have different dominant color casts. For example, daylight tends to be cooler with a bluish tint, while incandescent light is warmer with a yellowish or reddish tint.

Without proper white balance, these color casts will be reflected in the captured image, making whites appear tinted and affecting the overall color rendition. For instance, a photo taken under incandescent light without correct white balance might have a distinct yellow or orange hue, making skin tones look unnatural. Similarly, a photo taken under blue-toned daylight might appear too cool.

The purpose of white balance is to compensate for the color temperature of the light source. The camera analyzes the scene and adjusts its color sensors to make any white object in the image appear as white as it would look to the human eye under that specific lighting condition. This adjustment effectively neutralizes any color cast from the light source, allowing other colors to be reproduced accurately.

Most digital cameras offer automatic white balance (AWB) settings, which attempt to intelligently determine the correct white balance for the scene. However, for more precise control and consistent results, manual white balance settings are available. These include presets for common lighting conditions like daylight, cloudy, tungsten, fluorescent, and flash, as well as a custom white balance option where the user can manually set the white balance by photographing a neutral gray or white card. Properly setting the white balance is fundamental to achieving accurate and pleasing color reproduction in photographs and videos.
