Correct spelling for the English word "white balance" is [wˈa͡ɪt bˈaləns], [wˈaɪt bˈaləns], [w_ˈaɪ_t b_ˈa_l_ə_n_s] (IPA phonetic alphabet).
White balance is a fundamental concept in photography and image processing that refers to the adjustment made to accurately reproduce the colors in an image as they appear in real-life under different lighting conditions. It is a calibration technique employed to ensure that the colors within a photograph appear natural and without any undue dominance of a particular color cast.
When capturing an image, the lighting conditions can have a significant impact on the appearance of colors. Different types of lights, such as incandescent, fluorescent, or natural daylight, emit different color temperatures and therefore affect the overall color rendition in a photograph. White balance allows photographers to compensate for these color temperature variations, producing images that more faithfully represent the original scene.
White balance can be adjusted manually by setting the camera to predefined settings such as daylight, cloudy, tungsten, fluorescent, or flash. Alternatively, it can be set automatically using the camera's automatic white balance feature, which evaluates the scene and adjusts the color temperature accordingly. Additionally, white balance can also be adjusted during post-processing using specialized software.
By properly adjusting white balance, photographers can avoid unnatural color casts and ensure that whites appear truly white, regardless of the lighting conditions. This adjustment helps to preserve the accurate depiction of other colors, enhancing the overall visual quality and realism of photographs.
The etymology of the word "white balance" involves understanding the origins of the two individual words it consists of: "white" and "balance".
Firstly, the word "white" has its roots in the Old English word "hwīt", which eventually evolved into "white" in Middle English. The Old English term can be traced back to the Proto-Germanic word "hwitaz", meaning "bright" or "shining". This word is related to other Germanic languages, such as German "weiß" and Dutch "wit".
Secondly, the term "balance" comes from the Latin word "bilanx", which means "two scales". It further originated from the Latin words "bi" (meaning "two") and "lanx" (meaning "dish" or "plate"). Over time, it evolved into the Old French word "balance", which eventually became "balance" in Middle English.
