I am a novice at Canon 60D 18- 135. But at night, the lights at home are yellow tungsten lamp, and the portraits are all yellow, and the faces are yellow. How to adjust them? Please ask questions.

There is no need to change m gear. The positive solution of white balance, adjust the tungsten lamp file, or the color temperature file is about 2800 ~ 3000 K, try to see which effect is better. However, the most convenient adjustment is to use RAW format to adjust the white balance in DDP later. Under normal circumstances, you can safely give it to automatic white balance, but if you encounter color cast, you must set it yourself.
