Well, it is really easy. First read the exposure of ambient light for the background. Second read the exposure for the figures. Now: Set the diafragman of your camera at the value of background. If the difference is 1 stop, set the flash to the same value than the figures. (figure: f:2.8, background: f:4, adjust your flash to produce an f:1.8) If difference is 2 stops set the flash to 1.5 stops over the figure (figure 2.8, background 5.6, set your flash to 4.5) If the difference is 3 stops or greater set your flash to the background. Figure 2.8, background 8, set flash at 8.
