2018 Light Workshop

TGA Lighting Handbook V1.0

 

1) Concepts of stage lighting

Most important things: 1) you need to be able to see the actors 2) What you are doing has to look good on stage.

Areas of acting. How to divide the stage. Use areas and lights to create different environments.

Use lights to attract the eyes of the audience and to focus towards what you want them to see. Lighting helps to reinforce time and place.

You are able to control lighting intensity, color, and transition speed.

Intensity helps determine: 1) what you want people to focus in 2) The environment in which the scene happens

Transition speed: Make sure to balance your changes, and to avoid transitions that are too sudden. The eyes get tired.

Angles of lighting: Front, sides, back.

Front diagonal top: Most used. From 2 sides. Lights both sides.

Front top: Projects light downwards. Creates a lot of shadow on the floor.

Front straight: Follow spot. Shadow on walls.

Side top: Cenital/spotlight. Creates shadow towards the floor and on the face. Spooky.

Front/side bottom: creates shadow towards ceiling and on face.

Back lights: Create contrast. Commonly used with colors. Make actors pop put from scenery. Creates shadow towards front. Dramatic.


2) Concepts of color usage

Color serves to change the environments. Examples.

Cold colors vs warm colors. Cold colors (blue, white, green, purple) are associated with night and calm. Warm colors (red, yellow, orange, pink) convey feelings of joy and vitality.

Best color for skin are amber, lavender, light pink.

Color mixing, RGB.

Gels, LEDS.

5) How to hang lights

How to aim the area of acting you are looking for. Near/far.

How to attach clamp, hang light, apply safety chain, focus.

Connect to ceiling. Ceiling plugs are numbered. Numbers correspond to cables in lighting room, which are then connected to the dimmer packs, which are controlled by the console.
