How to set the white balance when shooting in a sports cup with sonya7?

When shooting with a digital camera, the correct white balance conditions should be selected according to the shooting environment or light source type and the approximate range of color temperature. Generally, high-powered iodine tungsten lamp is mixed with natural light in the gym. The comprehensive color temperature varies according to the intensity of iodine tungsten lamp or natural light. The comprehensive color temperature is about 3000K (mainly for lighting) ~6500K (mainly for indoor natural light with high color temperature). At this time, as long as the white balance of the camera is set to "Auto", you can take excellent photos. Especially for advanced models like Sony A7, you don't have to worry about putting the white balance on the automatic gear in the gym.
