When shooting video, try to use one type of light source per shot. While this generally isn’t a concern – especially if you’re shooting outside – problems can arise when filming indoors near windows. In such cases, the camera picks up both sunlight and indoor lighting (fluorescent, incandescent, etc.) and the resulting picture looks abnormal. The two types of light have different
color temperatures, each affecting your camera’s exposure differently. If possible, use either sunlight or artificial light, but not both unless you know what you’re doing. And remember, always white balance when shifting locations or light sources.
