![Page 2: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/2.jpg)
Introduction
Films consist of pictures and sound.
The pictures come from cameras, but cameras
need light to see.
All around us, there is plenty of light
“accidentally”, from ambient daylight, room
lights, etc.
![Page 3: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/3.jpg)
Introduction
On location, it is the lighting team’s job to:
1. Use and supplement, or
2. Eliminate the “accidental” light
In the totally controlled studio environment, all
light has to be provided for the cameras

1. Limit light
2. Reduce shadows
3. Overlap adjacent lights

Lighting Mood
Lighting helps to establish the mood of your
story.
Changing the angle, intensity, and colour of
your lights can dramatically alter the mood of a
scene

Common Lighting Terminology
Ambient light
The light already present in a scene, before any additional lights are
added.
Incident light Light seen directly from a light source (sun, lamp, etc).
Reflected light
Light seen after having bounced off a surface.
![Page 22: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/22.jpg)
Common Lighting Terminology
Colour temperature
A standard of measuring the characteristics of light, measured in degrees Kelvin.
Contrast ratio The difference in brightness between the brightest white and the
darkest black within the image.
Key light The main light on the subject, providing most of the illumination and
contrast.
![Page 23: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/23.jpg)
The Correct Way of Lighting
There is never a correct or definite way.
There is always scope for interpretation and trail
& error in lighting.
![Page 24: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/24.jpg)
The Correct Way of Lighting
The best way is to ask these 2 questions:
1. How do I light the scene logically and realistically?
2. Where is the light for the scene coming from?
![Page 25: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/25.jpg)
Angle of Shine
The imagined source of light for a scene representing
the sun shining downwards
What is your angle of shine in order to recreate the light
from the sun?
![Page 26: Lighting intro -_day_9.ppt[1]](https://reader033.vdocuments.site/reader033/viewer/2022042813/54b8d8cc4a7959ff278b4762/html5/thumbnails/26.jpg)
Managing Shadows
In the natural world, objects often only cast one defined
shadow
How do you light your shot to achieve one clear defined
set of shadows?
