The process of removing unrealistic color casts so that objects that appear white in person are rendered white in your photo.
White balance is crucial for accurate color reproduction in digital photography. Different light sources (sunlight, fluorescent, tungsten) have different color temperatures measured in Kelvin. Proper white balance ensures that white objects appear truly white, not bluish or yellowish. While modern cameras have automatic white balance, understanding manual white balance settings helps in challenging lighting situations or when trying to create specific moods in your images.
