FRONT VIEW: Here you can see all three lights: the main light in front, the hard light behind her on the right, and the softer, but still focused, light with the strip bank on the left. Although the strip bank sends out a thinner column of light than a standard large softbox, by putting an egg crate grid in front of that, it narrows the beam even further and makes it more directional. Perfect for hair or rim light.
LEFT SIDE: In this shot, you can really see the right rear strobe, and the metal 20° grid snaps directly into the reflector (well, at least the one I use does. Depending on your reflector, you might have to use black gaffer’s tape to hold the grid over the reflector).
RIGHT SIDE: In this image, you can see that I’m not standing directly in front of the subject—I’m standing a few feet off center, aiming almost directly into the strip bank on the left side (the one with the egg crate grid)—and that’s what’s creating the “lens-flare” look.
BACK VIEW: Again, we’re using a 20° metal grid on the right rear strobe, and the degree determines how narrow the beam created by the grid will be. A 30° grid would create a wider beam, and a 10° grid would create a very thin beam, like a really powerful flashlight.
