Understanding
Lighting
Lighting is the
art of setting light to the camera using lighting equipment able to see
objects clearly, and create the illusion that the audience gets the
impression of distance, space, time and atmosphere of an event displayed
in a staging. Like
the human eye, video cameras need light enough to function effectively.
By
lighting the audience will be able to see what the shape of the object,
in which he interacts with other objects, the environment, and when it
happened.Electronic camera work is
strongly influenced by the lighting system. This is
consistent with the character of the image recording system by an
electronic camera, so that the problems regarding lighting a very
important role in image recording activity.The
light source is divided according to the source of natural light, such
as sunlight (natural light / daylight) and Light created or sourced from
the light, the fire (an artificial light / tungsten)The light source itself has
the characteristics of light source and light intensity varies. We ignore this problem, we try to treat a
system that is applicable to the work kamera.Seperti basic lighting
theory. In every shot is
influenced by the existing lighting conditions, whatever the conditions
but results have also followed the lighting conditions. But to get the maximum results then we can follow
the basic lighting theory applies, although in practice we can develop
our creations as you wish, and the results will be achieved.
QUALITY OF LIGHTa. Hard lightCalled the harsh light generated
from the light source with high intensity, light is more spot. Produces high contrast and harsh shadows (dark -
bright).b. Soft
LightAlso called a soft light as
generated from the source terpendar and smooth usually light emitted is
a flood and, coupled with a filter or a smoothing element pemendaran
cahaya.Kontras produced thinner so that the image produced is not too
hard.
Light by lighting the basic concepts can
be distinguished:a. Natural LightNatural light sources of
light in a frame or scene adengan and sourced from the light that is
natural. For example, the morning light from the east (key). Then the shot-shot scene is key lightnya preformance from the
same direction.c. Pictorial Light / Light
arificialThe light that is artistic or creation. formed according to the needs of the artistic, the mood a scene
or a scene. So the direction of the light source (key) can vary
according to the needs of artistic images or mood of the scene.
Direction of LightLighting is distinguished by the
direction of light and the light falling on your subject can be
distinguished:a. Top LightLight coming from the direction of the subject,
as the ambient / base also creates a depressed mood light on the
subject.b. Eye
LightLight
directed at the eye position of the subject in order to strengthen the
power generated from the eye.c.Accent
LightThe light that is
created as an accent beyond the subject to create depth and a certain
mood. Usually
aimed at the backgroundColor Temperature (Color Temperature)Different light temperatures will produce different color
temperatures. Fluorescent lamps provide light bluish green, halogen
bulbs produce tangsten reddish yellow, the sun emits rays of light
bluish white color.The difference is actually due to differences in the degree
color temperature measured in Degrees Kelvin.The lower the degree Kelvin, the temperature of reddish
color, while the higher degree Kelvinnya the temperature tends to a
bluish color.

If we look at the sun or
other man-made light, the incandescent light produced is white or
yellow. So the light is a blend of several different sources HUE

human eye.
2. TATA BASIC PRINCIPLES OF LIGHTThis has become the basis of a
formula or a formula lighting in video production, film, and
photographs. Three important points were made up:
Key Light, Fill Light, Back Lighta. Key LightThe main lighting directed at the object. Keylight
is the most dominant source of lighting. Keylight is
usually brighter than the fill light. 3 points in the design of lighting, Keylight placed
at an angle of 45 degrees above subjek.Fill Lightb. Fill lightLighting fillers,
typically used to remove object shadow caused by the key light. Fill light is placed
opposite to the subject of the same length with Keylight. The intensity of lighting fill light is usually half of the key
light.c. Back
LightLighting from behind objects, serves to not give
dimensions so that the subject does not "blend" with the background. 45
degrees of lighting is placed behind the subject. The intensity of lighting depends backlight illumination key
light and fill light, and of course depending on the subject. Eg backlight
for the blonde will be slightly different with the lighting for people
with black hair.3. Lighting functionLighting comes on
stage and illuminates all objects actually presents the possibility for
directors, actors, and the audience to see each other and communicate. All objects
are illuminated gives a clear picture to the audience about everything
that will be communicated. With light, illusion imaginative
director can bring. Many things can be done with the role of lighting
bekaitan but the basic function lighting there are four, namely light,
dimension, selection, and atmosphere (Mark Carpenter, 1988).- Lighting. This is the most basic function of
lighting. Lights shed light on players
and every object on the stage. The term illumination in the stage lighting is not
just a light effect that can be seen but to enlighten a certain part
with a certain intensity. Not all areas of the stage have the
same level of light but arranged with the purpose and specific intent
that confirms the message that would be submitted through the behavior
of the actors on stage.- Dimensions.
With the lighting depth of an object can be imaged. Dimensions
can be created by dividing the dark and light sides of the object
illuminated the stage so that helps perspective. If all
objects are illuminated with the same intensity the image to be captured
by the eyes of the audience to be flat. By setting the intensity level and the
segregation of dark and light sides of the dimensions of the object will
appear.- Selection. Lighting can be used to determine the object and
want to irradiated area. If in the film and
television director can choose scenes using the camera do it with light
stage director. In particular staging, the audience can normally see the entire
stage area, to focus attention on a particular area or action directors
take advantage of the light. This
selection is not only influential to the attention of the audience but
also for the actors on stage and presented the beauty of the stage.- Atmosphere. The most interesting of the lighting
function is its ability to bring the atmosphere that affect audience
emotions. The word "atmosphere" is used to describe the atmosphere and the
emotions contained in the incident light lakon.Tata able to deliver the
desired atmosphere by the play. Since
the discovery stage lighting technology, lighting effects can be created
to simulate moonlight and the sun at certain times. For
example, the color is different from the morning sun during the day. Morning sun brings warmth during the day while
the sun was hot. This is the picture of the
atmosphere and emotions that can be generated by lighting
The
four main functions of lighting above does not stand alone. That is, each function having interactions (interplay). Lighting
functions performed by selecting a particular area to give a
dimensional objects, mood, and emotion events. The following figure shows the interaction of the principal
functions of lighting.
In addition to
these four basic functions above, lighting has developed support
functions differently by each expert lighting. Some support functions can be found in lighting
are as follows.- Motion. Lighting is not static. Throughout the
performance, the light is always on the move from one area to another
area, from one object to another object. Motion light flowing movement
that is sometimes the changes realized by the audience and sometimes
not. If the transfer of light moving from one actor to another
actor in a different area, the audience can see it clearly. But the change of
light in the area when the scene was in progress sometimes not directly
aware. Unknowingly brought to the
audience in a different atmosphere through changes in light.- Style. Light can show style
performance was dilakonkan. Realist
or naturalist style that requires detailed reality requires lighting to
follow the natural light such as the sun, moon or table lamp. In the Surrealist
style lighting is projected to present imagination or fantasy outside
everyday reality. In the comedy or slapstick staging lighting requires a high
level of illumination so that any motion made by funny actors can get
caught clearly by the audience.-
Composition. Light
can be used to create the painting stage through order of the resulting
colors.- Emphasis. Lighting can give a particular emphasis on a cool
scene or object. The use of color and intensity can attract the attention
of the audience so that helped a message that would be submitted. A high portion of the building that is always lit
throughout the show will attract the attention of the audience and
raises questions that make the audience to investigate the purpose of
it.- Marking. The light serves to alert during the show. For example,
fade out to end a scene, fade in to start the scene and black out as the
end of the story. In traditional theater, black out is
usually used as a sign of changing scenes accompanied with a change set
4. Lighting
Equipment
Work lights are rays of the setting
work on stage. Proficiency in mendisitribusi light
on the stage is needed. With
lighting equipment, control or control over the distribution of light
is created. Stylists need to control light intensity, color,
direction, shape, size, and quality of light and motion light flows. All the controls
that could be possible because of the lighting equipment is designed for
the purpose. Mastery of the equipment required to be learned by
the lighting.a. BulbBulb (bulb, lamp) is
the light source. The parts of the envelope
consist of a bulb, filament, and the base (Gb.204). Envelope
is a shell made of glass or quartz glass to protect components from the
air and prevent it from fire.Gb.204
BulbFilament is an electrical component that
converts heat into light. The size and shape adapted variety with heat resistance and
yield light chill. Because of the hot filament to produce light so he also became
weak because of the heat so it can be easily damaged. It
is therefore fitting and release the bulb should be done with caution
especially when the condition is on. Base, is a
heavy foundation to put the bulb in a suitable holder and is a component
of the connecting filament with electrical current. Types and forms of different
base. This
is in accordance with the holder provided for each lamp type and brand
of a particular manufacturer.
The
picture above shows the variety of bulb shapes. Almost
all of the bulb is made separately with reflektornya but the light bulb
PAR is a unit with a reflector and a lens so if the bulb is dead then
all unit components must be replaced. Basically the type of light bulb stage three, namely;
tungsten, tungsten-halogen, and discharge. Tungsten is used for under
1000 watt lights. Tungsten-halogen lamps for 1000 watts and above. While the discharge is a light
that can only be operated manually as followspot lights. Usage is based on the
type of bulb withstand the high heat resistance of the material within a
period of time. Because it works with
hot, then the quality of the bulb decreases with time and use his
deadline (lifetime) has been determined (limited).b. Reflectors and
ReflectionTo emit light from the
bulb to the object illuminated reflectors needed. The only light coming from the light bulb is
less strong and directional radiance. With reflectors the light emitted
from the bulb can be upgraded, organized, and directed. Stage light using three types of
reflectors, namely; ellipsoidal, spherical, and parabolic. Ellipsoidal reflector arch-shaped half-ellipse (oval)
surrounding the light beam that created the three-dimensional effect. Distance
on each side of the light source remains. Because of the
shape of the light produced by the ellipsoidal reflector has two focal
points (tittik Intersection focus light). Focal point 1 comes from
the focal point of the light source (bulb) and then bounced back into
the reflector which results reflections form 2 new focal point spread
(Gb.206).
Gb.206
Reflector elipsoidal
Spherical reflector has a rounded
shape side. This
type of reflector to direct light from the emitting entire focal point
of the reflector that reflects it back through the focal point before it
dispersed. If the line is an imaginary circle of light that reached the
length of each line is the same light. Figure 207
shows the reflection of light through spherical reflector.Gb.207 spherical reflectorThe
parabolic reflector has a parabolic shape. This type of reflector
to direct light reflected from or through the focal point and then
spread in parallel to form a light whose diameter is almost equal to the
diameter of the reflector (Gb.208). Thus, the diameter of the light produced depends on
the diameter of the reflector. Examples
lights everyday who use parabolic reflector is a flashlight.Reflection Gb.208 prabolicBesides
reflection generated by the reflector, the light will also undergo
radiation reflection after touching objects. Reflection of light that bounces once on the object can be
divided into four types, namely specular, diffuse, spread, and mixed. Specular
reflection (like a mirror) reflects light without changing the direction
of the natural light from the source (Gb.209).
Specular Reflection Gb.209Diffuse
reflection occurs when light bounces off the surface of the object to
glow evenly in all directions (Gb.210). Examples of diffuse reflection is when light is directed onto a
two-dimensional painting.
Gb.210 diffuse reflectionReflections spread as diffuse reflection but
the percentage of each of the lines is not the same light. The light on the object with higher intensity lines and the
reflected light will memendar longer than the others (Gb.211). An example is when the light reflection spread the wad
of aluminum foil.
Reflection
Gb.211 spreadMixed reflection, a reflection of
the diffuse and specular mixture. Several lines
dipendarkan light equally in all directions but most of the lines over
the light reflected like a mirror (Gb.212). Examples of mixed
reflection is when light is shining on the door handles of metal, gold
watches, or that shiny wood floors.Reflection Gb.212 mixedc. LensRefraction
or bending of light requires that the small size of the light can be
adjusted. The
tools used to refract light is a lens made of glass or plastic kind. There are three types
of lenses used in the stage lights, the plano convex lens, fresnel and
pebble convex. The
lens plano convex outer side concex (curves) and had a smooth surface
(Gb.213). The lenses are commonly referred to as the PC is
used to form a circle of light around the edges line clearly visible
(hard edge). The
size and thickness of the lens depends on the size and intensity of
light desired results.Gb.213 planno convex lensFresnel
lens is a lens forming mold surface ragged (Gb.214). Lights that use these
lenses will produce halos that line the edges soft (soft edge). The
thickness of the fresnel lens is thinner than a PC lens. Soft lines halos produced
allows for mixing colors on the irradiation area. While
pebble convex lens has a lens outer surface with the PC but it jagged
like fresnel (Gb.215). These lenses are often referred to as step lens. Character of light it produces is between PC and fresnel.Gb.214 fresnel lensGb.215 pebble convex lensd. LightThe term light is used here does not refer to the word
but lantern lamp. The word is defined as a lamp and lantern as a light
bulb and all equipment including the bulb. The term lantern used as a differentiator between the stage
lights to light the home. In the stage lights there are many kinds
of lights. However,
fundamentally categorized into two types, namely flood and spot. Flood has a light beam has a beam
spread, while the highlight spot directed. All
lamps have a distinctive feature for producing light. Technological development stage lights sometimes produce
something new by combining the principles and elements in it. The main task of the present stage lights are light, colors,
and shapes that can be adapted and directed according to the needs.1. FloodlightThe simplest form is the realm of stage lights
floodlight (Gb.216). Bulb and reflector
placed in a box that can be directed to the right and to the left and up
and down to adjust the light fall. No other special arrangements that can be done
such as setting the size, shape beam, and focus. Nature
of the spread of the light rays generated makes the irradiated area size
depending on the distance the lights of the object.Gb.216 floodlight lampsBecause of its limitations, ineffective flood lights
used to illuminate the actors. Its range makes light rays rely blur on objects far away. The area flood light irradiation depends on
wattage and reflectoris used. Thus,
the standard flood lights with 1000 watt power capable of illuminating a
wider area than a power of 500 watts. Effective use of flood lights to
illuminate the backdrop (siklorama) or specific objects at close range. Watt flood lights that use a large
and devoted to illuminate the backdrop called cyc-lightGb.217 Cyc-lightFlood lights can be combined by stringing a few
lights in one container (compartment). Colors are arranged so that in one case there are
several lights that have the same color. Some flood lights
that are strung together in one box and hung on the stage is called a
batten or striplightGb.218 Batten or striplightThe
function of these lights is to illuminate the backdrop or siklorama
from above. But if the circuit is placed
under the front of the stage in order to illuminate the actors from the
bottom called footlight. If the circuit is laid down but not at the front of the
stage in order to illuminate the backdrop or a specific object from the
bottom called groundrow.2. ScoopLights scoop is flood lights which uses
ellipsoidal reflector and can be used for various purposes. The resulting light beam evenly with radiating soft
(Gb.219). Scoop lights there are several
types that are designed specifically for a particular bulb. Some use regular incandescent bulb is using tungsten
bulb. But in general, the scoop can use an
incandescent bulb and a tungsten-halogen. These
lights are very efficient to illuminate certain limited areas. Character soft light makes the light
scoop is ideal for integrating light color. Besides being used to stage theater
and puppet theater, the scoop is also used for television, studio
photography, and buildings that require special lighting such as
museums.Lights Gb.219 scoop3. FresnelFresnel spot lamp has a borderline soft rays of
light. These lights use a spherical reflector and
fresnel lens (Gb.220). Because
the character fresnel lens that ridges on the outer circle of the
central part of the light produced brighter and dimmer light towards the
margins. Setting the
size of the light beam is done by moving the bulb and reflector lens
approach. The
closer to the bulb and reflector lens the circle of light rays produced
increases. The nature of the soft circle of light
allows two or more colors of light combine fresnel lights on the object
or area is irradiated. Lack of fresnel lights is
the highest light intensity was at the center of the circle of light so
that if an actor standing slightly jauk from the center of the circle of
light so he gets less pretty light.Fresnel lights are made
with a wide variety of lens size and strength (power) as shown in Figure
221. Lens size and power of lighting affect the results.
