Chapter 13 Flashcards
Fundamental Objectives of Lighting:
- Exposure and visibility
o Most rudimentary and utilitarian function - Depth and dimension
- Narrative emphasis
- Tone and mood
- Consistency
-Make sure your lighting schemes remain consistent!
Natural light
a term meaning a lisght source coming from nature, a source that is not artificial
Artificial light
any light source that generates light through electricity
Available light
light sources that ordinarily exist in any given location
Mixed lighting
combining light sources of different color temperatures (Aaron’s def)
Motivated lighting
using movie lights to duplicate where light would logically be emanating from
Intensity
- the strength of the light emitted b a source and is measured by a light meter in footcandles
- Depends on reflector system
- Depends of wattage of the lamp used (500 watts, 1000 watts, etc)
Inverse Square Law
the intensity of light falls off by the square of the distance from the subject
Point source
where the light glows white hot, creating a directional beam
Hard light
light that travels from a lamp directly to a subject
Diffuse light
light that does not directly illuminate the subject, but instead reflect light off an unpolished, white surface
Color temperature
the tonality that a light favors
Tungsten lights (quartz lights)
common for artificial lighting instruments for medium-scale film and DV production (color temp. – 3200K degrees) – quite warm
HMI
commonly used in bigger production (color temp. = 5600K degrees)- designed to emit a light that matches daylight color temp.
Gels
sheets of dyed plastic material that are used in front of a lighting unit to alter the quality of that particular light source BEFORE it falls on the scene
“tough”
heat resistant and can be placed on barndoors
Neutral density
gray and do not affect the color of a light source: they simply cut down on its intensity
Camera filters
glass or hard plastic elements mounted in front of the camera lens to change the quality of the light, from all sources, entering the camera
Matte boxes
attach to the front of the camera and extend out from the lens to keep unwanted light from glancing off the lens
Neutral density filters
gray tinted filters that simply cut down the amount of light entering the lens
