Introduction test of the second lesson

Welcome to your Exit test of the third lesson

An iris is

system of shutters with which the light beam can be cut into a certain shape

mechanism that allow reducing the light beam by its closing

color mixing of green, orange, blue and olive color

steel or glass template that releases the light in a certain shape or pattern

If you want to focus a light beam on the actor during an important monologue, which type of light are you likely to use?

Floodlight

Backlight

Spotlight

Sidelight

What is the most common advantage of PAR’s in a theater?

The possibilty of adjusting the light beam.

Outgoing strong beamed light, small weight and cheap to buy.

Combining with floodlights for the cyclorama lighting.

Small weight, the low price and flooding the stage by light.

In PARcans we using these types of optical lighting sources

narrow spot, medium and flood

circular, rectangular and oval

red, green and blue

spot, frost and open

The color of tungsten lighting sources in conventional lights is a kind of

warm with more red and yellow rather than blue

warm with more yellow and blue rather than red

cold with more red and yellow rather than blue

cold with more blue and red rather than yellow

What is focal length?

The distance between source of light and audience.

It is a measure of how strongly of light is focused onto the lighting area.

It is a measure of how much the system converges or diverges light beam through the lens.

It is a measure of how much all the lighting instrument help the actors to be better seen.

Fresnels deliver

hard light, which is also ideal for long throws.

soft light, which is also ideal for long throws.

hard light, which is also ideal for short throws.

soft light, which is also ideal for short throws.

Follow spot

PC with barndoors

Scoop

PAR

A follow spot is by deafult equiped with

barndoors

shutters

IRIS

fresnel lenses

If it is convenient to create a large surface that is covered with monochrome color, which device might be preferable as such?

Scoops

PARs with flood bulbs

Floodlights or cyc lights

Fluorescent tubes.

Can the beam spread of Ellipsoidal Reflector Spotlights be adjusted?

In some cases.

No.

Yes.

Only with using gobo.

A gobo is

system of shutters with which the light beam can be cut into a certain shape

mechanism that allow reducing the light beam by its closing

color mixing of green, orange, blue and olive color

steel or glass template that releases the light in a certain shape or pattern

Cyc lights are

floodlights with an asymmetrical reflector, used for cyclorama lighting.

Fresnels with an asymmetrical reflector, used for cyclorama lighting.

Fresnels with an symmetrical reflector, used for cyclorama lighting.

PC's with a symmetrical reflector, used for cyclorama lighting.

Which type of a lantern produces such a beam of light?

Floodlight

Fresnel

ERS / Profile spot

Pinspot

PC and Fresnel are both spotlights, but there is a difference between them in

the type of the lens.

the type of the construction.

the type of the reflector.

the type of the source of light.

Which kind of device this symbol stands for?

Fresnel

Spotlight

Floodlight

Parcan

ERS / Profile spot

Follow Spot

Fresnel

PAR

If you would like to create a shape square on the stage by light, which type of these devices would the purpose suit well?

PC with barndoors

ERS / Profile spot

Flodlight

PAR

What a followspot is usually used for?

For pick up the main character or another stuff on the stage and give him the special importance. (manually controlled)

For following the director's commands

For the audience entrance

For pick up the main character or another stuff on the stage and give him the special importance. (automatic controlled)

Which type of a lantern produces such a beam of light?

PAR

Scoop

Fresnel

Dimers allow changing the intensity

the brightness of the luminous flux of sources of light

the intensity of the luminous flux of sources of light

the color of the luminous flux of sources of light

the beam angle of the luminous flux of sources of light.

Main feature of moving heads is

manual operation with many functions

possibility to be remote controled from the lighting console

they need to be connected into the dimmer circuit

just only combining the colors

Floodlights are not equipped with

Reflector

Power cable

Optical system

Yoke (Lyra)

Essential characteristics of lighting instruments are

luminance, brightness, beam angle.

spill, beam angle, luminance.

spill, edge quality of the light beam, brightness.

beam angle, spill, edge quality of the light beam.

Fresnel produces a light beam of

equal distribution with a soft edge.

equal distribution with a hard edge.

unequal distribution with a soft edge.

unequal distribution with a hard edge.

The PC and Fresnel are both spotlights, but the main difference between them is

the type of lens

the type of the reflector

the Fresnel can't be equipped with barndoors

the PC can't be equipped with barndoors

The light beam of Fresnel has

Hard edges with no spill

Hard edges with large spill

Soft edges with large spill

Soft edges with no spill

Can the light from a PAR(can) source be shaped?

No.

Yes.

It depends on the brand.

Only rarely.

It is possible to use gobo with Fresnels?

Yes

Only indoors

Only when used together with PAR’s

C.T.O. (Color Temperature Orange) filters is usually used to

to change the color temperature of tugsten sources to cold light.

to change the color temperature of discharge sources to cold light.

to change the color temperature of discharge sources to warm light.

to change the color temperature of incandescent sources to warm light.

Which type of a fixture produces such a beam of light?

PAR

ERS / Profile spot

Scoop

Hint

Fresnel has

a lens with concave circles.

a lens with concentric circles.

no lens.

a lens with concave ovals.

Moving heads with discharge bulb have color mixing system of

scroller

RGB

CMY

HSB

What kind of a lighting instrument this symbol stands for?

Fresnel

Profile spot / ERS

Scoop

PAR

What is a “channel” used for?

It connects lights and console.

It controls the lighting devices.

It specifies the number of the fly bar where the light is hanged.

It creates a light “curtain”, which is largely used in dance.

A PAR(can) with halogen bulb provides light that is

bright with an oval beam that cannot be shaped, just rotated.

bright with a rectangular beam that can be shaped and no rotated.

bright with an oval beam that can be shaped and rotated.

dull with a circular beam that can be shaped and no rotation needed.

What a scoop is usually used for?

General lighting

Actors lighting

Special lighting

Down lighting

Moving heads generally have these functions

pan and tilt movements

gobo and color mixing

dimming and prisma

dimming, pan and tilt moving, color mixing, zoom, iris, gobo, prisma...

Spotlights (PC and F) generally produce light with

soft edges; it can be further shaped with the help of barndoors.

blurred edges; it can be further shaped with the help of shutters.

blurred edges; it can be further shaped with the help of barndoors.
