各位：係維港夜晚時影人像加維港夜景用不用較白平衡？

Sunlight WB produces yellow photos because the colour temperature at night is low, but it gives a warm feeling. If you don't mind, use sunlight WB; otherwise use tungsten light WB. If you take portraits at night, use sunlight WB instead because the people turns terribly blue under tungsten light WB.

The color temperature of flash is about 5500 degree K which is the same as day light.

If flash light is used day light white balance should be used to match with the flash light color tempreture
