LIGHTING







The technique of adding

light and color to a scene

Lighting



• Approach:

• Consider the effect you want to

achieve... bright & open, dark &

mysterious, shadowy and intimate,

'natural,’ soft/harsh

• then devise a method for achieving it.

Other factors



• talent movement (sitcoms lit brightly to

accommodate movement on 'stage'...

lighting generally not key to story)



• type of production - hard news,

magazine/depth interview style,

narrative

Other factors



• goals of production



• availability of equipment and time

constraints

Lighting Units (fixtures,

housings)

• Spots



• focused beam, bright, intense



• lamp (bulb) moved to focus/flood beam



• very common

Fresnel (freh-NEL)

Barbizon link







• Very common studio and field light



• Adjustable bulb - slides back and forth

within the light housing



• Special lens at front of light - circular

pattern adds both focus and diffusion to

the light beam

Ellipsoidal (Leko)



• complex lens system



• very precise, less common, studio only



Barbizon link

External reflector spot

• ”Field" light w/moveable bulb

• Very common in field production

• 1000W Lowel DP Light

• Chimera Soft Box

• 650W fotolite

• Barn doors

• 250W Lowel Pro Light

• Umbrella mount

Flood



• diffused light, reduces/fills shadows

• scrim can be added to increase

diffusion

• Scoop -fixed" bulb, soft light

• Broadlight - "box" shaped, may have

many lamps, used in studio or field.

• Lowel Tota light - 650W

• Often used w/umbrella

• Built-in barn doors (2, not 4)

Elements (bulbs)



• INCANDESCENT - typical light bulbs,

yellowish color

• QUARTZ/HALOGEN - very bright and

hot

• 3200K

• - handle w/care: use gloves, oils from

hands can ruin bulb

• HMI - halogen-metal-iodine - 5600K

• bluish light, not as common

Mounting devices



• Lighting grid - mounted on ceiling,

12-20 feet high (studio only)

• C-clamp (studio) - connects to grid

• Light stands (field) - tip easily, use

sandbags if possible, be careful when

extending fully

• Various field light clamps - ceiling

clips, door mounts...

Brightness control



• Studio lighting control panel - all

lighting inputs controlled from panel



• Dimmers - in-line power controls which

enable lights to be dimmed (make sure

light wattage doesn't exceed dimmer

capacity [e.g., 600 watts])

Diffusion devices

• Goal - soften light and shadows, reduce

harshness

• Reflector umbrella - light faces away from

the camera, bounces off of umbrella (think

'senior portrait').

• Soft box - nylon box mounts to lighting unit

with a wire frame, white material softens light

• Diffusion gels - different materials which

soften light, connected with clothes pins or

gel frame

Diffusion continued

• Bounce light off the ceiling/wall to create a

diffused light on the subject.



• Bounce-fills - white/gold nylon on

expandable frames to bounce light onto fill

side of subject. Very useful in the sun or with

only one light.

• - put bounce on opposite side of key light

• - use a C-stand if possible

Diffusion continued



• Silks/scrims (some bounce fills can do

this too)





• Reduce the amount of sunlight falling on

talent (creates shade) a C-stand if

possible

Direction control



• Barn doors - fit onto lighting unit, help

"shape" light



• Snoot - same, circular pattern ('coffee

can' on front of light helps really narrow

beam)

Color Gels



• colored acetate mounted on front of light

• adds color to light



• can be used to 'correct' color (turn tungsten to

daylight temp or vice versa)

• CTO - orange, makes daylight warmer

• CTB - blue, makes lighting units match sunlight

LIGHTING TECHNIQUE

• 3-POINT LIGHTING - basic method

• KEY LIGHT - main light source on subject

• focused, tight beam

• creates strong shadow

• vertical angle: 30-40 degrees

• too low - reflection, shadows on wall

• too high - shadows on face

• side angle: 15-30 deg. to side of camera

• Instruments - Fresnel, ellipsoidal, external

reflector

3-Point Lighting cont’d.



• FILL LIGHT - soft, diffused,

• - opposite side of camera from key light

• - removes shadows from KEY

• Elements: scoop, broad, flooded

Fresnel or external reflector w/diffusion

• One person's key can be another's fill.

3-Point Lighting cont’d.



• BACK LIGHT lights the back of the

subject

• highlights edges, back, hair

• separates subject from the background

• higher angle than others - 45-50 deg.

• so it won't spill into camera lens

• can be mounted low (rim light)

OTHER LIGHTING TECHNIQUES



• BACKGROUND lighting

• - lights the 'background'

• - be selective and careful, light

separately

• - color helps separate subject from

background

• - gobos, 'cookies' can shape light, add

patterns to light

OTHER LIGHTING TECHNIQUES



• KICKER - low level light, lights specific

item or area on set



• Trend is toward lower overall light

levels, more naturalistic lighting

Some basic lighting suggestions:



1. Be very aware of the direction, color and

intensity of light when setting up on

location.

• Where is the light coming from?

• Can it be controlled, eliminated?

• What color is it? Is outside light bleeding

in? What can we do about it?

• Is light too intense? Too soft? How can

this be adjusted?

Some basic lighting suggestions:



2. Don't set lights until camera position

and talent position have been

determined. Don't set camera and

talent until lighting issues have been

considered.

3. Make sure you look through the

viewfinder when determining proper

light levels (don't just use your eyes).

Some basic lighting suggestions:



4. Do NOT plug lights and cameras into

the same outlets. Buzz/hum.

5. Never plug a light in with the switch in

the ON position (ALWAYS turn lights off

before plugging in).

6. Warn people that you are turning lights

on so that they don't get 'blinded' by the

light. “STRIKING!”

Some basic lighting suggestions:



7. Use gloves to handle lights once they

have been turned on - housings get

very hot very fast.

8. Never touch the bulbs with bare hands,

oils will cause them to break.

Some basic lighting suggestions:



9. Light foreground and background

separately. Light from main lights

should NOT also light the background.

• Provide plenty of room between subject

and the background.

• Light the background with separate

units.
