1 Lighting

2 Types of Light Incident: comes directly from the light source Reflected: has come in contact with some other material before entering our field of vision Our ability to see largely the result of reflected light

3 Lighting Director’s Goals Meet artistic needs of the program General Illumination needs Develops a lighting plan so that all performers and parts of the set are lit as required/desired

4 Measuring Light Levels Measured with a light meter Video levels? Audio levels? In footcandles (ftc)--amount of light falling on a surface one foot from the light with the illumination level of one candle Also used, lux: About 10 lux = 1 ftc Measure incident & reflected

5 Other lighting issues 1--Contrast Ratio: brightest to darkest: human eye 100:1, TV 30:1 Sports Stadium daytime shots (shader) Monitors and adjusts the iris opening AGC automatically adjusts 2--Color Temperature: measure of the frequency of the light wave 3,200° K / 5,400° K / red / blue

6 Lighting uses & objectives Flat Lighting (shape/texture) High-key / low-key for mood Follow spot, limbo (subject ‘in limbo’ against softly lit cyc/cameo (subject lit & background dark)/ silhouette (subject dark & background lit)lighting-focus attn. More specific definition to follow- - …cont...

7 Lighting uses & objectives To imitate reality Shoot on a set for ‘outdoor shot’ Using lights shooting outdoors Bouncing light shooting outdoors Use of shadow and lighting effects ‘Natural’ look / invisible lighting

8 Lighting Instruments Quartz lamp 3,200° K 500 / 1,000 / 2,000 watts / 10,000 New High Speed Fluorescent (HSF) Traditional / HSF at 3,200° K HMI bulb -- 5,500° K NEWEST – LED, 5500° K

9 Lighting Instruments Spotlights Controlled beam / pinned & spread Fresnel Other spotlights Ellipsoidal / leko / cutters / cookies Barn doors / light pole / light stand

10 Lighting Instruments Floodlights Pans/broads --rectangular shaped Scoop -- Bowl shaped Strip lights for background Softlight -- bulb points inward Sometimes covered with scrim or gels

11 Three point lighting Key --spotlight -- 35-40° angle Fill -- flood or spread spot (1/2) Back --spotlight (1.5-2x the key) Subjects and foreground Compare to background -- also important Kicker --comes from the side over the camera left shoulder of the subject (added to 3-point lighting) External lights must be eliminated / mixing light sources

12 Lighting effects Silhouette--subject is not lit; background is evenly lit Limbo--subject is lit evenly; background is vague or nondescriptive Cameo--subject is lit with a spotlight directly above; background is not lit

13 Studio Lighting Light Board / dimmers / pig tails Grid vs. floor stand Extension poles, c-clamp, safety Inverse square law--as light to subject distance doubles, light level is reduced to 1/4 previous level ###
