A device used in the film and television industries, as well as 6.1 Photographers, to modify properties of light. There are variations on types of scrim, depending upon its use, whether with natural light, or with man made light resources. However, their basic use is the same-to reduce intensity and/or hardness of light. SCRIMS

BOUNCE LIGHT

Flexfill reflectors. Useful for filling shadows and reducing lighting contrast. Available in different surfaces: white maintains the character of the light; silver for more punch over longer distances; gold for adding warmth; translucent softens the light. REFLECTORS

EYE/OBIE/BASH LIGHT A camera mounted lights that used for news gathering or documentary and feature films. A camera mounted light is useful when the camera is moving because the unit moves with the camera and provides shadow les light on the subject.

Newer type of lighting unit uses LEDs and offers lots of advantages for shooting. These compact units produce heat- free, flickerless, silent light and some units can be dimmed from 100% to full off with no color shift. LEDs are starting to replace other types of bulbs both in the home and on movie shoots because they are versatile and eco-friendly. LED LIGHTS

Spill light or spilled light usually from the edges of the beam that illuminates an area that you don t want it SPILL LIGHT CONTROL

Century stands have low-slung legs at different heights that allow several stands to be postponed close together. C-STANDS

LOCATION LIGHTING: POLECATS, ETC. A polecat is an expandable closet bar. A heavier-duty version is the wall spreader. Which allows you to run a piece of lumbar, such as a two-byfour, between two walls `

Used in theatrical lighting as in the home, to regulate light intensity. Dimmers lower the voltage going to the light. Which not only makes the light dimmer: but with tungsten lights results in the color temperature dropping as well (making tungsten lights more orange.) DIMMERS

LIGHTING RATIOS Lighting ratios are the comparison of key light to the fill light. The formula to lighting ratios is K[ey]+F[ill]/ F Fill is intended to be shadowless and light is intended to illuminate so when you combine the two lighting factors it revolves around the subject s face within a frontal shot. Ratios come out of powers of 2 and the stops represent an exponential increase in light. Ruby Barriga

MIXED COLOR TEMPERATURE Ruby Barriga Mixed color temperature gives any film or photo a touch of life. Light sources either natural or artificial, contain color that depends on white balance that allows color to present itself. When certain colors are portrayed certain emotion, and temperature give the story you re telling more clarity.

Gels: CTO & CTB Ivan E CTO or color Temperature Orange is considered to put on our flash so that we can cool our background while still maintaining fairly white light on our subjects. CTO gels allow us to lower our camera's white balance and dramatically cool down our background. CTB or color temperature Blue, is primarily used to cool down warm incandescent lights so they appear closer to white light which reads around 5000k. They can be placed direct over or around your light source to help cool the color or warm hot lights. C T B C T O

Magic/golden Hour Ivan E The Golden Hour or Magic, occurs during the time just before sunset. and just after sunrise When the sun is lower in the sky, near the horizon, it must travel through more of the atmosphere, reducing the intensity of direct light and thus reducing the contrast in the scene. More blue light is scattered, so sunlight will appear reddish and shadows won t be as deep as when the sun is higher in the sky. The lower angle of the sun creates longer shadows, which can add interest to images.

Night/Day for Night Ivan E Day for night is a set of cinematic techniques used to simulate a night scene while filming in daylight. It is often employed when it is too difficult or expensive to actually shoot during nighttime. Because both film stocks and digital image sensors lack the sensitivity of the human eye in low light conditions, night scenes recorded in natural light, with or without moonlight, may be underexposed to the point where little or nothing is visible. When shooting day for night, the scene is typically underexposed in camera or darkened during post production, with a blue tint added.

LIGHTING VOCABULARY BY: Ana Paula D, Jackie O, and Sebastian P

Tungsten-Halogen-Quartz Definition: A type of blub which employs tungsten filament surrounded by halogen gas encased in a quarts glass blub. most commonly used bulbs for professional lighting instruments

HMI LIGHTS Definition: Bulbs that are efficient lighting source that produces daylight-balanced illumination put out three to four times as much light as tungsten bulbs

FLOURESCENT BULBS Definition: compact fluorescents bulbs Usually found in homes, offices, intuitional settings and units for film and video work

PLUSGREEN/MINUSGREEN GELS Definition: Gels that add a green cast are called plus green. Gels that remove the green cast of fluorescent lights are called minus green. gel converts tungsten light to 'daylight' color

SPOTLIGHTS (FOCUSING) FRESENAL LENS AND OPEN FACED SPOTLIGHTS Definition: Fresnel Lens emit focused, parallel rays of light that don t spread out much or diffuse over distance. Definition: Open faced spotlights are lighter and cheaper than Fresnel units and are often used on location and in small- scale filming

FLOODLIGHTS (PAR) SEALED-BEAMLIGHTS AND SCOOPS/BROADS Definition: PAR lamps are sealed beam lights that look like automobile headlights Definition: Scoops are dish shaped flood lights. Broads are rectangular and have a long, tube shaped bulb. Used as fill lights or provide illumination.

DIFFUSION MATERIALS LEE 216/250(1), ROSCO OPAL TOUGH FROST(2) AND ROSCO SOFT FROST(3) Definition(1) and (2): Professional diffusion such as translucent plastic sheets Definition(3): similar to a shower curtain material, flexible

Available Light Using what ever natural or man made light already in the location.

Naturalistic Light Using light from nature, or the environment like the sun.

Hard Light/Specular Light Direct light in a clear environment which makes parallel lines.

Soft Light/Diffuse Light Lighting made with rays that are going in different direction that produce a softer shadow.

Top Light/Under Light Light which shines down or up directly on the subject.

Lighting Contrast Difference in illumination of color that makes an object distinguishable. Low key: high lighting contrast High key: low lighting contrast

Wattage Ameasure of electrical power expressed in watts.

Inverse Square Law A law stating that the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source.

Lamp Head/Bulb Different types of bulbs like household bulbs, photo bulbs and LEP etc.
