1) Use a preset WB. These settings are simple to understand and can be useful when shooting under multiple light sources, which can fool Auto. Use Tungsten (usually denoted by a light-bulb icon) indoors under incandescent lighting—it makes the colors in photos less yellow (i.e., cools them down). The Fluorescent setting compensates for greenish artificial light, warming up your shots. Cloudy and Shade settings will also warm up cool, blue tones.
