Lighting ratios

In this image by Marcus Bell you have two lighting ratios present. On the bride, there is a rather stealthy ratio of 4–5:1. This was caused by a single speedlight positioned in one of the window alcoves. No fill was used so the ratio is steep. Because of light scatter, the ratio on the groom is less than 4:1—although the light intensity has dwindled because of the distance from the flash.\n
