Honl modifiers used on this shoot:
To light the character Zira, I used a 1/8 Speed Grid with a 1/4 CTO Filter as the main light, just to the right of the subject. This light gave a focused beam on the face, and was positioned so a small bit of light spilled over to the left side of the face. I added a speedlight with a Speed Gobo and 1/2 CTO Filter at a low position on the front to provide a bit of definition in the costume, part of it spilling on the left side of the face for an additional fill. The speedlight was set at a lower power than the mainlight, to provide fill, but maintain the drama of the lighting. The green fabric background was lit with a speedlight outfitted with a Speed Snoot in the reflector position with a 1/4 CTO Filter, which provided a fan-like spread and a nice falloff. Power settings will be different depending on which model of speedlight you're using, but a good guideline is to start with your main light, and adjust your power settings on the rest of the scene to fit your tastes.
All speedlights are kept relatively close to the subject at around 4 feet, so I was able to maintain an aperture of f/5.6, 1/60 second at ISO 200.
