    A GUIDE TO LIGHTING IN EDUCATIONWhatever the scale of a production - amateur or professional - lighting like other design processes is based on a sequence of logical

    decisions plus a good measure of creative inspiration.

    This brief guide offers a sequence of step-by-step decisions to form the basis of a lighting process for the smaller scale production. It

    has been prepared by a lighting designer with experience of working on productions of all types and sizes. Strand hope that it will be

    especially helpful to amateur groups, small touring companies and educational theatre.

    Types of Light

    How do we choose which type to use in each position? As Strands lighting equipment is so robust choice is further complicated, in that in

    addition to the range in today's catalogue, many earlier models are still in use. However lighting instruments group into families and it isconvenient to consider our requirements in terms of what each family offers in terms of beam size, beam shape, and beam quality.

    Floods

    The beam size, shape and quality emitted by a flood is fixed: there are no adjusting knobs. The light is therefore suitable for lighting skies

    and cloths. It is not selective enough for lighting actors. Coda units may be single or grouped in 3s or 4s for colour mixing. They have a

    reflector that is specially designed to ensure an even wash over a large area from a short throw

    Soft Spots

    Prism Convex (PC) spots allow control of the beam size, and the beam may be roughly shaped by a rotatable barndoor. The quality is even

    and soft-edged, with less light-spill outside the main beam than in the case of a fresnel. In addition to the PCs, Fresnels have a very soft

    edge. The beam angle is adjustable and its shape roughly containable by a 4-leaf rotatable barndoor. The extent of the spill outside the

    main beam makes them unsuitable for longer throws, particularly from the auditorium.

    Profile Spots

    Profile spots give precise control of the beam. An iris diaphragm (for round edges) and shutters (for hard edges) can produce shapes in allsizes. For more complex shapes, special masks can be cut. Edge quality can be adjusted from very soft to very hard by moving the lens,

    while a metal pattern plate called a gobo can texture the quality of the whole beam. The number in the profile's name indicates the beam

    angle.

    Whereas standard profile spots have a fixed beam angle, which is narrowed by shuttering, variable beam profiles use a pair of lenses whosedifferential movement gives a wide range of beam angles and edge qualities. The shutters are then only required for shaping. Adjustments

    are faster and more efficient use is made of the lamp's output The number in a variable profile's name indicates the range of available

    angles.

    The SL New Generation Profile Spots now provide increased light output with reduced power consumption. Often referred to as a

    coolbeam profile, they do this by using state of the art optical coating on a glass reflector, allowing the optical light to be passed forward,

    while the heat and infra red spectrum is allowed out of the rear.

    Beamlights

    Most lighting instruments produce a conical beam so that the spread widens as the throw increases. Beamlights use a parabolic reflector

    (and no lens) to produce a near parallel beam which is more intense than a lens spotlight of the same wattage. This is one of the moreimportant developments of the past decade. The optics are fully contained within the glass envelope of the lamp. Various Lamps providing

    angles of a squashed near-parallel beam are available. The intensity produces a depth-enhancing haze in the air, so intense that it is

    effective even with deep colours. The basis of most rock lighting today.

    CHOOSING

    LIGHTING

    POSITIONS

    Lighting from the frontConsider the effect of a light starting

    as a vertical downlight on an actor thenmoving in a frontal plane until its beam

    becomes horizontal and then carries onto light from below. How visible will be

    the actor's face, particularly eyes and

    teeth? To what extent will face and

    body be modelled or flattened? What

    area of stage will be selected and what

    will be the size and direction of

    shadows cast on floor and scenery?

    A vertical beam is the most selective

    light possible. The lit area of stage,

    and the shadow cast upon it, need be no

    wider than the widest part of the actor.

    However, the actor's eyes will be blackpools and a highlighted nose will shade

    the mouth.

    If the light comes from a little forward

    of the actor, it will start to reach the

    eyes and mouth (provided that shekeeps her chin up and is not defeated

    by a hat brim!). However, the lit area,

    and shadow cast, starts to extend

    upstage from the actor - i.e. the light is

    slightly less selective.

    As the lighting comes increasingly from

    the front, the actor's eyes and teethreceive more light. But the area lit

    extends further and further upstage,reducing the selectivity and increasingthe likelihood of the actor's shadow

    hitting the scenery

    As the light becomes more and more

    frontal, the actor's features become

    flattened (and so also does three-

    dimensional scenery). The lit area andthe actor's shadows increase until,

    when the light is horizontal, there is a

    lit corridor for the entire depth of thestage, and the actor shadows become

    actor length.

    Light from below projects an actor

    shadow that looms above the actor

    rising and falling as she moves towards

    and away from the light source. Whenthis is the only lighting angle, the

    effect on the face is not at all natural.

    But a little from below, usually just

    reflected light can help to soften the

    harshness of light from above.

    Lighting from the back

    and side

    Now consider a light from behind.

    Then a light or lights from a series of

    side angles (i.e. lights at right anglesto those considered above). Once again

    the criteria is visibility, modelling,

    selectivity and shadows.

    A light source behind the actor does

    not illuminate the face, but it helps togive depth to the stage by separating

    the action from the scenery through

    creating a haze and highlighting headand shoulders. The shadow of the

    actor is cast forward, helping theselection of areas. Since the light does

    not fall on the face, strong colours can

    be used.

    If the light comes from a little to one

    side of the actor it will start to reach

    the eyes and mouth on that side. The

    area lit, and the shadows cast, willextend along the stage floor on the

    other side.

    Add a second light source from the

    other side, and both sides of the face

    will receive light. However, there is

    now a second shadow and the selected

    area of stage floor extends to both

    sides of the actor.

    As the side lighting comes from an

    increasingly lower angle, the shadows

    will lengthen to both sides of the actor

    and a larger corridor will be selected

    across the stage. As the light hits the

    face from a lower angle, it will light

    more into the eyes and teeth, although

    there will still be a tendency towards a

    central dark line where the beams meet

    down the centre of the face.

    As the angle lowers, sidelight has anincreasingly modelling effect on the

    actor's face and body. This is

    particularly important in dance. When

    the light becomes horizontal there will

    be a lighting corridor across the whole

    stage. By focusing just clear of the

    floor, it is possible to lose shadows into

    the wings, and the light will only be

    apparent when an actor stands in it.

    Finding the compromise

    We normally seek to light an actor for

    maximum visibility and maximum

    modelling, with minimum shadow.

    Additionally in many productions, we

    need to select as tight an area as

    possible. Which combination of angles

    offers the optimum compromise?

    The basic compromise that has long

    been the standard approach is a pair of

    beams crossing on to the actor (one for

    each side of the face) from positions

    that are both forward and to the sideof the actor. The suggested angle isoften around 45 degrees in both

    directions - i.e. midway between

    vertical and horizontal and midway

    between front and side. However to

    restrict the shadows cast and to give a

    better 'join', the lights are often

    positioned closer to the vertical and tothe centre.

    A backlight added to the basic crossed

    pair brings depth to the scene and

    generally enhances the 'look' of theactor. The backlight can be used for

    strong atmospheric colour if required,while the crossed pair maintain a more

    natural tint on the actor's skin tones.

    Note: The actor is now It by three

    beams with a 120 separation between

    them.

    The problem with 'crossed pair' lighting

    (with or without a backlight) is the

    extent of the spread of light on floor

    and scenery beyond the area where the

    actor's head is lit (remember that headis usually about five feet above the

    floor). Although a single beam can be

    flat it can also be quite tight.

    Adding a backlight can enhance this

    flatness quite considerably - and the

    selectivity is still a tightly controlled

    upstage/downstage corridor withoutside spillage.

    For modelling, sidelights can be added

    and, although they will spread the lit

    area, they can be at quite steep angles

    since they do not need to make a major

    contribution to visibility. Note: Four

    beams now light the actor with a 90separation between them

    .

    SPECIALSThe major proportion of a stage lighting rig is focused to form a palette of areas and colours whose various combinations will provide the

    desired fluidity of selectivity and atmosphere. However there are certain lights whose function is so 'special' that they cannot make asignificant contribution when mixing the basic palette.

    For the Actor

    Specials usually consist of spotlights set so tightly that the spaces they light cannot be considered as areas. They are often for momentswhen an actor has to be picked' out (perhaps only head and shoulders) on an otherwise blacked-out stage. They need to be listed in a

    priority order for close scrutiny and reduction to essentials.

    For Special Effects

    There may be a request for equipment to produce clouds, flames, water, lightning, etc. When listing it is always prudent to remember that

    such effects can draw attention away from the actor rather than positively support a performance. And if the effect is essential, then the

    effect of light reflected from fire or water is often more telling than a pictorial representation of the actual fire or water

    For the Scenery

    The proportion of the rig focused on the scenery will be very small. With the exception of skies and back or front cloths, scenery normally

    gets sufficient general wash from the reflected light bouncing off the stage floor from the lights that have been set for the actors.Indeed, as discussed in the following pages, many of the basic problems of lighting design arise from difficulties in stopping actor light

    hitting directly on the scenery Successful lighting of scenery depends on augmenting the diffuse reflected general light by selective

    highlighting of chosen scenic elements, or parts of these elements. This can vary from bold gashes to soft emphasis. Again, to be listed

    and reduced to essentials after a debate based on priorities and available resources.

    DIVIDING THE STAGE

    Dividing by Area

    Once decisions have been made about the kind of contribution

    that we expect lighting to make to the production that we are

    planning - and these contributions have been put into some sort

    of order of priority - we need to break down the stage area into

    the segments over which we require independent selectivecontrol. The required breakdown may be symmetrical, in which

    case the stage plan will be divided into something that resembles

    a series of areas of different sizes corresponding to the placing

    of the action. Of course it could well be that there is no need

    for division into what it is useful to call production areas: all thestage may be in use all the time. In this case a simple division

    into centre and sides will allow balancing for maximum

    'enhancement' of the look of the scene.

    Note: Adjoining areas overlap - both side to side and back to

    front. And remember to remember that these are areas wherean actor's head is to be lit - they ore unlikely to be the some asthe light patterns on the floor

    Area planning for a play

    In this naturalistic play -possibly but not necessarily in a box set

    -the areas are determined to a considerable extent by the

    positions of furniture and doors. And the lighting is expected

    to make some logic in terms of practical light fittings (table

    lamps, wall brackets, etc.) and the natural sunshine and moonlight

    coming through windows (including those in the audience's

    'fourth wall'). In this particular example, we have a play where

    it is desirable to focus attention at various times on the sofa,

    the armchair, the table (with that essential tool of modern

    drama, a telephone) and the doors. These doors aretremendously important in any drama: some of the key

    appearances and speeches are made there. But for a longintimate scene on the sofa, it is useful to concentrate on that

    sofa and loose peripheral areas like the doors. Consider the

    seven areas shown here in terms of possible combinations: thearea palette gives the director a wide range of selectivity of

    audience vision - whether a subconscious fluidity (slow cues thatare not obvious) or an area selection obviously linked to the

    switching of the practical lamps

    Area planning for a musical

    Musicals tend to have many scenes and many selective andatmospheric light changes within these scenes. Therefore,

    unless there are many - very many - lights available, the

    breakdown into areas has to be very general. In this example

    the breakdown is symmetrical because, as in so many musical

    productions, the settings consist of a symmetrical series of

    wings leading to a backcloth, possibly a skycloth. With the

    addition of cloths and scenic pieces, the method of staging gives

    a flexible masked acting area with the possibility of sufficientopen space for dancing and lots of entrances for a large chorus

    to get on and off quickly In most musicals the big moments are

    staged in the downstage areas: to help both musical balance and

    the 'putting across' of numbers to the audience. For the same

    reasons, much of the essential action takes place centre stage.

    The most common selective lighting cue is to 'concentrate

    centre', usually downstage centre, by 'losing the edges'. Thissuggests a minimum of three areas across the stage - certainly

    at the front of the stage, and probably also midstage. However,

    it is often quite practical to consider the whole width of the rearof the stage as one area. This provides a seven area

    combination that offers an area palette giving the directorconsiderable selectivity with the possibility of progressive

    tightening from back to front and from sides to middle.

    Colour planning for a play

    In a naturalistic play, colour is often used to create a fluid

    atmosphere that can shift from warm cheerfulness to cool

    sadness. If an area is lit with some lights in warm tones and

    some in cools, the dimmers of the control board can be used to

    achieve a whole series of options from an extreme of the warm

    colour alone, through the neutrality of both together, to the

    other extreme of cool colour alone. Which (if any) of the areas

    need to have this kind of 'double cover' of colour tones? In this

    example, discussion with the director has established that such a

    colour palette seems necessary around the central areas and the

    desk, whereas the upstage corners and downstage right can

    manage on a warm tint only - although perhaps one that is a little

    closer to a compromise neutral than the warms in the mixableareas. In such a naturalistic production the actual colour tints

    chosen are likely to be quite subtle.

    Colour planning for a musical

    The dialogue scenes of a musical require the subtle colour tones

    that are appropriate for a naturalistic play However, the musical

    numbers, particularly when solo singers can be given isolating

    visibility from tightly focused follow spots, usually call for

    strongly atmospheric colouring. And many dance sequences,

    where the body is relatively more expressive than the face,

    respond well to positive use of quite strong colour This example

    shows a much used technique where the colour is applied in

    rather broader washes than the areas selected for scene

    location. The front half of the stage is divided into three areas,

    each lit from above in rather saturated colours: a hot and coldrather than a warm and cool. The rear half is treated as one

    area, also with a hot and cold from above. From the side comesfurther washes, probably in slightly less saturated hues. These

    may divide the stage into bands: in this case an upstage band and

    a downstage band, possibly splitting the stage into left and right

    but just as likely covering the full width. With relatively neutral

    colour from the front, saturated colours from above andintermediate colours from the side, we have a colour palette that

    offers considerable scope.

    THE DECISION PROCESSSo how does one decide where to put the spotlights? On many

    stages and in many auditoria there is not much choice: but, tomake the best use of the positions available, it is necessary to

    start from an ideal and compromise that ideal to fit reality. By

    WHERE, we mean where to put the light and where to point it.Traditional advice involves a lot of crossing of light beams -

    partly to help model/sculpture the actor by introducing apartially side-light angle and partly because lighting diagonally

    across a stage provides a bigger spread of light from each lamp:an important bonus when equipment is in short supply. Crossing

    the beams opens out the area lit but can cast excessive shadows

    on side wall or masking. And so, with spotlights becoming

    increasingly versatile as to beam width, there is every reason to

    consider using the traditionally discredited method of lighting

    the actor with light coming straight in from the front. Of course

    if this is the only light, yes it will be flat. (And if the available

    positions are so low that an actor shadow will be thrown on to

    the sky, then better to come diagonally - priorities again!) But

    with the addition of some backlight (even if it is nearly vertical)

    and some sidelight, the front-lit actors will come alive and the

    areas/ shadows brought more under control. There need not be

    precise side lighting for every area: it can often be quite generalsince it is frequently more important in the big wide areas than

    in smaller tighter areas (more important, that is, in priorityterms!).

    In the examples shown here, the traditional crossing method has

    been used for the play, while the actors in the musical are lit'

    flat frontal'. But it could be vice versa. Whichever way, the next

    stage in the planning is to establish where the lights go and

    where they point.

    Example plan for a play

    For each area of our play we need two lights. One for each side

    of the actors' faces. When an area requires a full colour control

    of cool and warm, the number will double to four spots - a

    crossed pair in warm and a pair in cool. A spot bar immediately

    behind the proscenium arch will give a suitable angle for lighting

    the upstage areas, but for the downstage areas a position in the

    auditorium is necessary Red and blue have been used to indicatewarm and cool filters in the spots. Green indicates more neutral

    washes that have been added from back and sides. Not enough

    equipment? Well, do we really need all these areas? And so many

    of them with both warm and cool? (Back to priorities?) Or rather

    than a pair, we could use a single straight in - but if so, we must

    make it really straight in because a single crossing beam does not

    do much for the other side of the face!

    Example plan for In the Round

    For staging in the round, light needs to come from all sides. Andit should be evenly balanced to avoid favouring one segment of

    audience to an extent that is not really permissible in a staging

    form so democratic as theatre-in-the-round. To avoid hitting

    into audience eyes, light has to come from both within the acting

    area and from outside it. Angles can be closer to the vertical

    than in other forms of staging because the audience is closer to

    the actors and thus visibility is 'easier'.

    Example plan for a musical

    In this musical the actors' visibility light is provided by spots in

    a neutral colour hitting straight in. The front areas are coveredfrom the auditorium, the midstage areas from a bar just insidethe proscenium, and the upstage areas from a midstage bar If

    the stage is very wide, two or more lamps may be required for

    each area as indicated. Strong colour comes from near verticalbacklights and medium colour from the wings (on stands, booms

    or ladder-frames to be discussed under 'rigging).

    Note: For clarity these plans only include actor lights. The play

    would require light outside the window and on the door backings,while the musical is likely to need a colour mix for the backcloth

    and possibly specials for elements of scener

    DECIDING WHICH LIGHTS TO

    USEDeciding which instrument to use obviously depends to a large

    extent on what is available - meaning another exercise in listing

    priorities. For 'foh' (front of house) throws of any distance inthe auditorium, profiles are essential, both to avoid undesirable

    lighting up of the auditorium from scatter light, and to allow

    sufficiently precise control of the beam to prevent spillage on to

    the proscenium. However in a small hall there is a lot of merit in

    considering fresnels or PCs (well barndoored) at close range

    when a lot of spread is possible from a few lamps. For onstage

    use, Fresnels and PCs come into their own with fast-to-set softedges - profiles are the most versatile instruments but they

    inevitably take longer to focus. For backlight, fresnels andbeamlights are favourite, while floods are to be thought of only

    for wide expanses of scenery. (Use for actor light only in

    situations of extreme desperation). For theatre-in-the-round,barndoored fresnels give the required smoothness and spread.

    Existing installations in most theatres and halls are likely to bebased on fresnels and profiles: anyone buying new equipment

    should look seriously at including a goodly proportion of the new

    generation PCs giving smooth soft-edge beams without stray

    scatter light and at the versatility of the variable beam profiles.

    This plan shows instruments being allocated to our play in a very

    orthodox way: profiles for the front-of-house and fresnels for

    onstage. If a couple of PCs were available, they would be a

    useful alternative on the ends of the stage spot bar: this is a

    position where any scatter light shows up badly on the side walls

    of the set. Whether 500 or 1000W units are required will

    depend mainly on length of throw, perhaps with the changeover

    around 6 to 8 metres. However, it is important always toremember that the actual level of light intensity is not so

    important as the BALANCE.

    Fresnels have been allocated everywhere because they have a

    good smooth spread (profile edges can be very difficult in small

    theatres in the round). Every spot must have a barndoor to

    contain spill from the audience eyes. Each become a pair of

    spots since this is the only way that it is possible to light fully to

    the sides of the acting area.

    Too many-spots? Then perhaps just one cover in a neutral shade

    (thereby halving the number on the plan) and utilising a couple of

    pairs of straight downlighters to add colour toning in warm orcool.

    The actor face lights are profiles from the front and fresnels

    onstage, with the second bar being less powerful units - face

    light is rarely important upstage in a musical. The backlights are

    fresnels, although parcans would be nice if available. For the

    sidelighting, profiles have been used downstage to contain the

    light in a tight corridor across the front - often advisable when

    front cloths or running tabs are in use. Midstage sidelighting use

    fresnels for a good spread, while the optional upstage sidelight

    again uses profiles to keep the light clear of the skycloth.

    THE RIG PLANTHE PLAN is the kernel of any lighting design. It shows, at

    minimum:

    1. The POSITION of each light.

    2. The TYPE of light in each position.

    3. Any ACCESSORIES, such as barndoors or gobo, required by

    any particular light.

    4. The DIMMER that will control each light.

    The plan should be drawn to scale (1" to I ' or 1:25). This helpsaccurate indication of light positions. And if scale symbols are

    used for these lights, there is a check on space problems: if it

    can be drawn on the plan, there will be room for it on the stage.

    Any shapes may be used to indicate lights, but plans are more

    easily read if the symbol resembles the outline shape of the

    light. Either way, the plan should certainly include a key showing

    the type of lighting instrument represented by each symbol.

    Colour and dimmer are indicated by number: the usual convention

    is to write the colour number inside the symbol and the dimmer

    number alongside the symbol.

    Lights fixed to horizontal bars are easy to show in plan: the bar

    can be drawn in the position that it will occupy over the stageand its height indicated by a note (such as + 14') written at the

    end of the bar. Lights fixed to vertical bars, or stacked on a

    series of brackets, are more difficult to draw - they must be

    indicated diagrammatically FOH lights in the auditorium are

    usually drawn much closer to the stage than their scaled real

    distance which would make the plan inconveniently large. The

    easiest method is to work on tracing paper over a ground plan of

    the scenery and stage.

    A good procedure is:

    1. Establish all lighting positions with Xs

    2. Convert these Xs to symbols of available (and/or acquirable)

    lighting instrument types, drawing them pointing in the

    approximate direction of proposed light travel.

    3. Write colour numbers inside symbols.

    4. Add dimmer numbers alongside symbols.

    5. Trace through key features of the set and stage - it is

    usually possible to trace through (in spaces clear of lighting

    drawing) enough to relate the positions of lights to the

    geography of the setting and stage.

    This will bring the plan to a point where it can be used to prepare

    and rig the equipment. The lighting designer's own copy will grow

    many extra markings to indicate precisely where the lights are

    to be pointed - markings so detailed that they would only confuseif included on all copies of the plan.

    LISTSFrom the plan, lists are prepared of the required number of:

    1. Types Of Light

    2. Lengths Of Cable

    3. Accessories

    4. Colour Filters

    5. Section Drawings

    Will there be borders to mask the lights (and other things)

    hanging above the stage? If so, draw a section to check that all

    the light beams will be able to reach all desired parts of the

    actors and the scenery. Usually (but not always) the heights of

    the borders and lighting bars can be adjusted. Only a sectionwill determine what these relative heights should be, and only a

    section will determine how effective the masking arrangementswill be for an audience eye in the front row.

    FOCUSINGFocusing is probably the most important part of the whole

    lighting operation. Not even the most sophisticated marvel of amicroprocessor control desk can fill in that dark spot where the

    lights have not been properly overlapped. Nor can a hard edge

    be softened or a disturbing spill on to a border be shuttered off.Focusing involves tricky ladder work so that there is every

    incentive to get it right first time - although, inevitably, it willbe necessary to get at the odd spotlight between rehearsals for

    a little fine adjustment.

    Focussing in comfort

    If you stand with your back to the light that you are focusing,

    (I) You will avoid being blinded (2) You will be able to see what

    the actor's light is doing to the scenery

    No clear shadow of

    head, therefore

    head is not lit.

    Clear shadow of

    If the lighting

    than the actor,make an allowance -

    What can we adjust?

    ON ALL LIGHTS

    Left/Right & Up/Down

    ON SOFT SPOTS

    Bigger/Smaller

    with optional Barndoor Rough shaping (& control of

    spill)

    ON PROFILE SPOTS

    Round size by optional Iris

    Shaped size by Shutters

    Texture by optional Gobo

    Beam edge quality by Lens and on Variable Beam Profile

    Spots

    Size and edge quality by differential movement of two

    Lenses

    Shape by Shutters

    The most difficult types of light are the basic Profile Spots

    since there is an interaction between shutters (or iris) and lens

    movement. Although adjusting the lens is principally a means of

    making the edge of the beam harder or softer, it will also change

    the size. Therefore it is usually necessary to adjust shuttersand lens alternately to get the desired combination of size and

    edge quality

    Most profiles have an adjustment whereby the light can be

    adjusted so that it is either smooth across the whole spread of

    the beam, or 'peaked' to be brighter in the middle with the

    amount of light falling off towards the edge. For most purposes

    it is easier to light with an even brightness across the beam andso it is recommended that anyone beginning to work with light

    should use an even beam until through experience they discover aneed for a 'peaky' beam.

    Ways The number of channels in a

    control system.

    Zoom A differential movement of
