This photography field notes introduces the entire process of taking high-quality photos on a basketball court with insufficient and uneven lighting, using two flashlights as cross lights and ambient light as auxiliary light. During the shoot, two small flashlights were used to illuminate half of the court, the camera was set to fluorescent white balance, and the methods of "cross lighting" and "long-distance hard light" were combined. Shooting from behind the basketball hoop towards the opposite side resulted in good lighting effects.
