Mixed lighting
Gemengde belichting · Light
A situation where multiple light sources with different colour temperatures are present at the same time.
A classic example: a room lit by windows (daylight, ~6000K) and incandescent bulbs (~2700K) at the same time. No single white balance setting makes everything look right. Approach: set white balance to the dominant light source. In post-processing (RAW) you can make local white balance corrections. Professional solution: use gels on flashes or lamps to bring all sources to the same colour temperature.
