Things You'll Need
Instructions
Set your poser up about 2 feet in front of your backdrop. This setup will separate your subject from the background and still eliminate unwanted shadows.
Place your main light at a 45 degree angle and about 3 feet away from your subject. This is the main light source and needs to be softened and spread evenly. Attach a softbox to the light head and notice how the light spreads. There is no harsh light in portraiture, so be sure to keep it soft and flattering.
Position the next light behind the camera and keep it at eye level with the subject. This is a directional light that applies directly to your subject. Notice the light reflecting in his her eyes. If it doesn't, readjust until it does.
Use a hair light to create further separation between your subject and the backdrop. This light belongs off to the side and should be fitted with a snoot to direct the light right at the top of the hair. If you don't have a snoot, fashion a cone with aluminum foil and attach it to the light with the point toward the subject.
Take a few test shots and tweek the arrangement if necessary. For a halo effect, use another hair light on the other side. Experiment with different setups and don't forget about reflectors to create subtle light on the face.
