The lighting in the studio.

I am a child photographer. 15 square meter should be enough for two lights, speed 125. The full aperture of light is 8 or 9. Let me describe it to you with the dial of the clock. For example, the photographer is standing at 6 o'clock, one light is at 5 o'clock and the other light is at 10 to 1 1. To make matters worse, the photographer has a light at 6 o'clock. At 4 o'clock, the other one is from 7 to 8 o'clock. For example, the photographer is at 6 o'clock and the two lights are at 3 o'clock and 9 o'clock respectively. Actually, there are many ways to chase me down and tell you more.
