(Allow discussion) SAY: It’s how a camcorder performs in low-light situations. Consumers will return a camcorder thinking it’s defective because the image looks “grainy” and lowquality. ASK: Why does their low-light footage look grainy and low-quality? What is the camcorder doing to compensate for low-light? (Allow discussion) SAY: Remember the gain controls? The camcorder is boosting the gain when switched to “low-light” mode. ASK: So, what is the key here? What is going to make these consumers keep their cameras instead of returning them? (Allow discussion; guide students to the realization that good video requires good lighting!) SAY: Lighting is a major part of getting quality video footage. That’s why you have an entire section of movie credits dedicated to lighting professionals. Eventually we’re going to learn about lighting techniques and how to properly control illumination. But before we get there, we have to learn about the equipment that will be used in lighting. Outline MI Outline (LSI Quadrant II): Instructor Notes: I. Use the slide presentation to introduce and discuss the following topics. Identify different types of lights used for studio and field productions. A. Spotlights 1. Characteristics Creates directional light Beam can be controlled or focused A spotlight shining on the ground will create a circle of light with definite AAVTC: Audio Video Production – Lighting Equipment Introduction Copyright © Texas Education Agency, 2012. All rights reserved. 2 edges Contains a lens 2. Fresnel Spotlight Named after the inventor who invented the lens in the spotlight Most common light in TV studios Can be identified by the rings of the lens Versatile Beam is adjustable from flood to spot Several sizes and wattages 3. Ellipsoidal Produces sharp, defined beam of light Beam can be manipulated with cookie/gobo, which is a cutout used to create a shadow pattern Beam can be manipulated with a shutter B. Floodlights 1. Characteristics Direction cannot be controlled Light goes everywhere Think of a flood…water spreads out and covers everything 2. Scoop Named for its round shape (think “ice cream scoop”) Fixed or adjustable focus No lens Gel holder around the opening 3. Broad Light Minimal beam control Diffused light Soft shadows 4. Soft Light Extremely diffused Very few shadows Various sizes Diffuser/gel holder around opening 5. Strip or Cyc Light Even illumination Used for cycloramas and set areas Great for background lighting 2. Identify tools used for directional control of illumination. A. Pipe grid Series of pipes strung in a crisscross pattern throughout the top of the studio Allows for placement of studio lights anywhere in the studio B. C-clamp Used to attach a lamp to pipe grid AAVTC: Audio Video Production – Lighting Equipment Introduction Copyright © Texas Education Agency, 2012. All rights reserved. 3 C. Safety chain Wire used as a backup support if C-clamp gives way D. C-stand (Century stand) Portable stand used for small, ENG/EFP lights 3. Identify tools used to control intensity of illumination. A. Barn doors Attachments to spotlights that masks off unwanted light to keep it from spilling into areas where it’s needed B. Flags Same as barn doors but not attached to light C. Screen Reduce light intensity D. Reflector Controls light direction, bouncing illumination toward subject 4. Demonstrate safe usage of lamps, bulbs, and lighting equipment. A. Safe usage for attaching studio lighting Be aware of amperage of lamp and amperage of circuit (30 amp light will overload a 20 amp circuit) Always connect lamps (lights) to pipe grid using C-clamp AND safety chain (backup) Make sure barn doors are also secured B. Practice proper ladder safety A partner holds the ladder while the other climbs Never move the ladder with someone still on it C. Safe usage when handling lamps Wear protective gloves to Adjust the barn doors of a spotlight that’s on; barn doors get very hot Replace a bulb; oils from bare hand will cause bulb to malfunction Make sure light is off and unplugged before changing bulb Adjust the light from behind it, not in front Avoid looking directly into lights that are on Note: If an accident occurs, REPORT IT IMMEDIATELY!

Make sure students are familiar with the materials to be used, proper techniques for handling materials, and safety procedures when dealing with lighting and electrical equipment. MI Independent Practice (LSI Quadrant III): Using the Lighting Equipment Lab, students should demonstrate proper techniques for handling materials and safety procedures when dealing with lighting and electrical equipment. Evaluate students on completion of the tasks that are available and applicable to your program. Allow four to five students at a time to complete this lab to avoid students standing around and waiting for their turn. Those not working on the lab may complete the worksheet (see review activity listed below). Summary MI Review (LSI Quadrants I and IV): Students will use their notes to complete the Lighting Equipment Worksheet. Students may work on this assignment concurrently while the lab exercise is going on. Evaluation is based on a 100-point scale. Evaluation MI Informal Assessment (LSI Quadrant III): Assess students during the lab assignment, monitoring their progress, and giving guidance and correction when needed.
