A participant in my photographing kids workshop took these three images, all with the same off camera lighting setup. The table in the shot represents a rectangle for lighting purposes. I placed 2 Speedlights diagonally across from each other, off each corner of the table. When the lights are diagonally across the rectangle you can shoot from any position around a straight edge of the table.
The flashes were placed in the plastic stand that comes with the flash and placed on some end tables. Then they were pointed up into the ceiling. The flashes were both tripped by the Canon 7D’s wireless system and I used E-TTL with a 2:1 ratio.
In the image above you can see the brighter of the 2 flashes is behind the girls creating a rim light in their hair.
In this image the brighter light is on the right. This time there faces are side lit.
In this image the brighter light is on the left side and the fill light is on the right side.
