The Key Light The Fill Light The Back Light O<span>nce you determine the lighting needs of your scene and set up the key, back and fill lights, you are almost ready to shoot. Always look at your scene through a viewfinder and on a color monitor if possible. You can fix weird shadows with fill light or changes in the key light placement. You can also fix reflections off glasses or bald heads by slightly moving the key or fill lights. Remember that light moves in a straight line and bounces at opposite angles. If you see a strange reflection, determine which light source it is coming from by placing your hand in front of the reflection and looking for the shadow, or turning off one light at a time until the glare is gone.
