Diffused Single Light for Large Groups

The more diffused a light source, the more power that light source will need to provide ample lighting. A diffused light source will appear bigger (or softer) than an unmodified light source, but not necessarily brighter; however, as the light source is bigger, the spread of light will become more apparent. To adjust for the added light spill onto the subjects closest to the light source, you will also need to add more distance between the light source and the group, which (when combined with the feathering technique) will allow you to light large groups more evenly.

Here is a diagram to further demonstrate how to use a diffused single light for large groups:

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