This information is a short introduction about lighting. It’s geared in direction of manufacturing Managers and manufacturing coordinators to develop their understanding of lights they might be requested to order for specific jobs. Lighting cameraman could discover some elements of the historical past of some lighting products fascinating so please learn on. This information may even assist with a few of the jargon utilized in TV Manufacturing.
In easy phrases lighting is cut up into 3 essential sorts, Tungsten, HMI & Fluorescent.
1) How does Tungsten work?
Nicely power is just handed via a really fine wire coil, (known as a tungsten filament) it heats up and glows ‘sizzling’ which in flip offers off light. The color temperature of the light is round 3200k (much like your bulbs at home)
2) HMI- what does it imply?
(Hydrargyrum Halide Iodide) lights have the identical color temperature as daylight (5600K to 6000K). They produce about 4 instances as a lot light as a tungsten bulb with the identical wattage. HMI lights work in another way from Tungsten in {that a} spark ‘jumps’ or ‘Arcs’ between two pins and that spark ignites a fuel which is held beneath pressure within the lamp housing. When that fuel glow’s it does so very brightly. These lamps require what’s known as a ballast. It is a heavy box that steps up the present and passes the excessive voltage to the lamp through a heavy obligation ‘header cable’. (Keep in mind by no means to look into an HMI when it is on, it might be like wanting straight on the solar!)
3) Fluorescent- is that like strip lights?
In a nutshell sure these are primarily based on the identical precept as home strip lights. They’re standard as a result of they’re light weight and provides off a beautiful soft light.
LIGHTS
Customary Interview Light Equipment
The equipment we’re most frequently requested to offer consists of 4 tungsten lights: an Arri 650-watt or 800-watt light with a Chimera, an Arri 300-watt light and a Dedo light. We additionally embrace a gel equipment with a variety of gels and a reflector.
This is a quick description of every light:
Arri 800-watt light (Redhead)
It’s an open-faced (there isn’t a lens in entrance of the bulb) tungsten light. For interviews, this light is mostly used with a Chimera (extra on Chimeras in a minute) as a key light, the principle light used to light a topic’s face.
Arri 650-watt light (mizar)
It is a Fresnel light – it has a lens with raised round ridges on its outer floor that are used to focus the beam. It’s usually used as a substitute of the Arri-800 and in such cases is mostly supplied with a Chimera. For interviews that is typically used with a Chimera as a key light. Nevertheless you may also connect a gobo and this light can be utilized to throw a slash of color on the background.
Arri 300-watt light (Mizar)
Just like the 650-watt light, it is a Fresnel light. For interviews, it’s generally used as a fill light – a light to melt any shadows created by the important thing light, typically with some diffusion gel (extra on gels in a minute) to scale back its depth. These lights are additionally used as a backlight in an interview – a light directed from behind the topic to spotlight the highest of the pinnacle and shoulders.
Chimera
A Chimera is also referred to as a lightbox or soft box. It suits onto a light utilizing what’s known as a velocity ring which inserts the place the barn doorways are held in place. You take away the barn doorways and put the velocity ring of their place. The Chimera appears a bit like a box fabricated from white and silver materials. It attaches to the velocity ring and sits in entrance of the light in order that the light shines via it. The impact is to melt the light, turning a harsh supply right into a diffuse one.
Trivia: The Chimera Lightbank was invented within the U.S. by a location photographer and a mountaineer to produce photographers with studio high quality lighting on location. They based the company CHIMERA in 1980 and function from Boulder, Colorado. Their products proceed to be made within the U.S., sewn in seamstress’s houses, and are individually inspected and initialed.
Velocity Rings:
Gels
Gels are fabricated from gelatin and are available in numerous colors on rolls. They’re reduce into sheets to suit after which mounted on the barn doorways of the light utilizing crocodile clips (much like clothes pegs solely they’re steel). Gels are an important a part of any light equipment. They can be utilized for color correction or to create particular lighting results. Understanding this requires a primary understanding of color temperature. Totally different sorts of light sources have totally different quantities of crimson or blue in them and might have an effect on the color of the picture you are taking pictures. For instance, tungsten lights have a special color temperature than daylight. This implies for those who had been taking pictures in a room with numerous daylight coming in and also you needed to light a topic with tungsten lights you’ll have an issue. One answer is to make use of color correction gels in entrance of the tungsten lights. These gels will make the light from the tungsten supply the identical color temperature because the incoming daylight. Different gels are used to diffuse or soften the light. Others could make the light extra flattering for interview topics. Some are used so as to add color to a light supply and solid that color within the background.
Dedo Lights
These lights had been designed by a German Director of Photography (DOP) named Dedo Weigert. Therefore the identify Dedo. They’re small and compact and have a light output equal to a lot bigger lights. In addition they supply precision control of the beam of light they produce. For interviews, they can be utilized as a backlight or to spotlight options within the background behind the interview topic.
Different Tungsten Lights
Arri 1,000-watt Fresnel Light
In the identical vary because the Arri 300-watt and 650-watt Fresnel lights, this light has a lens with raised round ridges on its outer floor which is used to focus the beam. The 1,000-watt light is mostly used for serving to to light an indoor location.
Arri 2,000-watt Light (Blonde)
Moving up from the redhead (800-watt open-faced light) you will have the blonde. This light is mostly used to assist light indoor places though I’ve recognized some folks to make use of it for serving to to light an interview.
Fluorescent Lights
Kino Flos
Kino Flos are fluorescent lights mounted in specifically made fixtures to carry two or 4 two or four-foot tubes. They generate a cool (within the “not sizzling” sense of the phrase), soft, vitality environment friendly light that’s wonderful for interviews and for lighting folks basically. They’re used as a key light and solid a soft diffuse light over the topic which could be very flattering. They’re a superb various to utilizing a tungsten light with a Chimera. One other benefit is that they take each tungsten and daylight tubes so you may simply use them in indoor places the place there’s a giant window or skylight that permits numerous pure light.
Trivia: They had been invented by the gaffer, Frieder Hochheim, and his greatest boy, Gary Swink, on the movie Barfly in 1987. These two innovators had been working in a cramped inside location and the DOP was utilizing a large angle lens. This meant there was no area to place a traditional lighting rig. The answer – fluorescent lights that may very well be hidden, simply mounted and managed with quiet distant ballasts. As a result of they do not warmth up, they’re wonderful for those who’re taking pictures in the identical location for a substantial time. They had been a real hit with the solid and crew of Barfly and are actually utilized in motion pictures and TV manufacturing everywhere in the world.
We continuously present Kino Flos to shoot interviews with celebrities and different excessive profile expertise. They’re standard in interview satiations as they don’t generate the Sam warmth that tungsten lights do. The vary contains: 4 x 4-foot tubes in a fixture; 4 x 2-foot tubes in a fixture and 4 x 2-foot tubes in a fixture.
Diva Lites
Manufactured by Kino Flo, these are additionally fluorescent tube lights.

The result’s a soft light that smoothes tough edges and flatters the expertise. It has a palm-sized ballast that mounts on the camera and runs off the camera battery. The equipment additionally features a matte-box tray holder. We’ve got used this light in studio and on location for static pictures and for monitoring pictures. Within the case of monitoring pictures it affords a constant flattering light. When the camera will get near the topic, a horny catch light produces a white ring within the eye which could be very flattering.
HMI Lights
They’re primarily utilized in indoor places with plenty of ambient daylight or open air throughout daytime hours.
