In the photograph of the model above, the key light is on the left, just as it's shown here. For the sake of consistency, the 45-degree angle will be used throughout this discussion. It's not unusual for a large set in a major dramatic setting to require more than 100 lights. The simpler the design, the better the effect. Note the catchlight effect in the photo of the model at the beginning of this section.
Numerous lights hitting talent areas also create a confusing horde of shadows.
Barn doors and flags can be a great help in keeping light out of unwanted areas. The Key's Vertical Angle W e have established the horizontal angle for the key light is approximately 45 degrees to the left or right of the subject in relation to the camera. As shown below, this angle is also commonly 45 degrees for the key light. We'll cover the other lights shown later. Sometimes in limited on-location conditions this may be unavoidable.
