CyberCollege TV Production Modules 31 - 35
When doing a segment outside in sunlight, a fill light could be in the form of
an HMI light; a quartz light with a blue filter; a white reflector board
Soft lighting can be used to minimize
wrinkles on a face to make a person look younger; depth and texture; surface detail
In formula lighting the angle formed between the key and fill lights should be about
45 degrees
In color television if a key light is 1,200 lux with formula lighting the fill light should be
600 lux
The light which is stronger than the key light and separates the subject(s) from the background with a subtle rim of light is called
a back light
An 8:1 lighting ratio would create
a rather dramatic effect
The "Rudolph effect" is caused by having the
back light too high
In formula lighting the fill light should
be half the intensity of the key light
In deciding on whether to key a person from the left or right you should
do what's most practical; adhere to consistency; follow source; consider the person's best side
In planning lighting it's best to
light for the camera angles responsible for close-ups
If you wanted to bring out maximum surface detail in a subject you would
not use a scoop for a key light; not use a scrim over the key light; not use color balanced fluorescents for a key light; not make sure the fill is next to the key
If you use a reflector board outside as a fill it should be placed
on the opposite side of the subject from the sun's illumination
In formula lighting the key light
primarily defines the texture, shape, form, and dimension of subject matter; is typically in the middle of the hard-soft range in light quality; is normally placed at about 45-degrees off to one side of the camera
In standard formula lighting the background light should normally be
two-thirds the intensity of the key light
If you use sunlight coming through a window as principal source of illumination on a subject and you want to use an incandescent light as a fill, you would need to
use a blue filter over the incandescent light
If you want to exaggerate (maximize) surface detail on a subject you should
use a hard light source; use a high lighting ratio; position the key from 60 to 85 degrees off to one side of the camera
To minimize shadows on a background you should
use backlights; put the subjects as far from the background as possible; use background lights
If you wanted to create a silhouette effect for a subject you could
use only a back light or a background light
