Single Light Feathering

While stacking flashes together, in essence, creates a “single” light source, the direction of each of the stacked flashes can be shifted to cover more ground. What happens when you only have one light as the light source? How can you feather a single light? The answer lies in how you direct that single light. When placed off camera to the side of a group, the single light can be directed toward the far side of the group (farthest away from the light source) so that the light falloff will still light the side of the group closest to the light source.

Here is a diagram to demonstrate single light feathering:

Here are the key steps for using this technique to photograph a large group:
