Otis College: How to Set Up, Light and Photograph a Green Screen

644 views 2 weeks ago
DEFINITION OF TERMS USED:

ISO -- in digital photography the ISO sets the degree of light sensitivity of the image sensor as designated by the rating system developed by the International Organization for Standardization (Note that it is a misconception that ISO stands for "International Standards Organization," ISO is derived from the Greek isos, meaning equal.)

SHUTTER SPEED -- Shutter speed controls the duration of an exposure. The faster the shutter speed, the shorter the exposure time.

ƒ-STOP -- Sets the size of the adjustable aperture inside the lens. This aperture controls the amount of light transmitted to the camera. The ƒ-stop numbers indicate the size of the aperture in relation to the focal length of the lens. The smaller the ƒ-stop, the larger the aperture opening, i.e., more light to the camera. The larger the ƒ-stop number, the smaller the aperture opening is, resulting in less light being transmitted to the camera.

KEY LIGHT -- is the main light in your scene and creates the visual sense of light direction in the shot. Or it is the light that has the greatest overall effect on the image.

FILL LIGHT -- is a secondary light or reflector that illuminates the shadow areas.

EDGE LIGHT -- or rim light. This is a light position behind or pointed from one side or the other of your subject. It gives the subject a rim of light that serves to separate them from the background.

SEPARATION LIGHT -- generally this is a light with a MINUS GREEN gel, used to neutralize the green spill on the foreground subject caused by the green screen and its lights.

KELVIN --The visible light spectrum as scientifically described in terms of color temperature. A light's color temperature is measured in degrees of Kelvin (K).

TUNGSTEN LIGHT -- The color temperature of the lamp is 3200 Kelvin (tungsten balanced.)

DAYLIGHT BALANCED LIGHT -- For Kino Flo KF55, color temperature of the lamp is 5500 Kelvin (daylight balanced.)

CTB -- Stands for color temperature blue. A full CTB gel converts tungsten light of 3200K to "daylight" color (5500K). This gel will reduce the output of your light by 1.5 stops.

MINUS GREEN -- Is a magenta gel used to remove green spill on your subject.
