notice the labels on the pictures. white balance is measured on a
kelvin scale, which is a temperature. it's the same temperature scale on the boxes of fluorescent light bulbs at lowe's or home depot. the higher the temperature, the warmer the color (orange and red hues). conversely, the lower the temperature, the cooler the color appears (blue and greenish hues). a textbook photo has a perfectly balanced white point for true color reproduction. you can purposefully alter the white balance from its neutral point to emphasize something in the photo that you feel is there. color is a strong tool because it can evoke different emotions and feelings. subtle differences can make a big impact. take the next three photos for example. same photos, different white balances. do you see and feel the difference?
