LIGHTING
Lighting can be analyzed by the
following four characteristics
1
| QUALITY (relative focus of the
illumination) |
HARD
- Directed, focused light
source
- Parallel light rays
causing clearly defined shadows, sharp edges, crisp
textures
- Created by sun light at
noon or by a light source which is lensed, like as
Fresnel light (spot light).
|
SOFT
- Diffused, unfocused
light source
- Creates softer shadows,
blurred contours and textures
- Created by overcast sky
or light source which is softened by a diffusion
filter, gel, or scrim.
|
2
| DIRECTION
(path from source to object lit) |
- frontal -
eliminates shadows, flat,
- sidelight -
sculpts features of subject
- back light -
from behind the subject -
- when used alone,
it creates silhouettes
- when used in
combination with other (frontal) lights,
creates a contour around subject (rim of
light)
- under
lighting - distorts, horror,
fireplace...
- top light -
glamour (accentuates cheekbones) or darkened noir
(as in single bulb hanging above the
detective)
|
3
| SOURCE
(From what source does the light come from?
What is the lighting contrast ratio?) |
- High Key:
- lighting set up
that is uniformly bright
- It comes from many
sources to create lighting which is flat - not a
lot of contrast between bright spots and
shadows
- usually used for
comedies, light dramas, adventure
films.
daylight, indoor at a
supermarket, the classroom, most common studio
lighting set up
|
- Low
Key:
- lighting which has
high contrast ratios
- It comes from
realtively few soursces to create a set up that
is mostly dark with some clearly defined bright
areas
- Often with hard
lighting - but NOT ALWAYS
- aka "chiaroscuro"
- dark darks and bright spots of
light.
- film noir,
mystery, studio work in Zed TV on CBC

COLOR
Different colors can
create different emotions, moods, and
illusions. |
TYPICAL LIGHTING SET UP
(3-point
lighting)
FOLLOW THESE LINKS FOR EXTERNAL TUTORIALS ON 3-Point Lighting,
Key Lights,
Fill Light,
Back Light, and Background Light
- The primary light
- the dominant source of
illumination.
- brightest
- In set-up, it's usu. 45 degree
angle to camera
- less intense than key
- fills in, softening or
eliminating shadows - i.e. lessens contrasts.
- usually next to the camera or at
45 degree ablge to camera opposite the location of the key
light.
- Fill could be provided by a
bounce card or reflector to reflect a soft light on
subject.
- comes from behind and above the
subject
- usually opposite the key
light.
- used in studio
productions
- when used with key and fill, it
creates a rim around subject (glamorous)
- creates spatial relief -
separates subject from background.
- creates a sense of
depth
- BACKGROUND LIGHTS or
SET LIGHTS:
- used to illuminate the set or
the background (walls, furniture, etc)
- SPOT HIGHLIGHTS or
EFFECTS LIGHTS
- extra light that accents a
portion of the setting with intense or patterned lights for
dramatic effects
- blinds on a wall,
e.g.
- any light that is already in the
picture.
- Although they can provide light
to illuminate the scene, they do not necessarily have to,
they're often used to just give the illusion of
light.
- candles, a small desk lamp,
matches. etc...
Disadvantage of 3 point set up is
that you have to rearrange the lights everytime you change camera
position of subject(s) position.
