Using natural light from incoming windows is a great strategy for home movies, quick-down-and-dirty shoots and large locations that are impossible to light without a crew of twelve. Using natural light can save you time, money, and hassle.
But often, your video will look best if you use supplemental lights.
Technically, a picture is nothing BUT light. This is true for video pictures too. The quality of light is the single biggest determinant of the quality of your video. Ideally, you should not only have adequate light, you should also have mood-appropriate lighting. Amazing affects can be achieved if you know how.
Light fixtures used for professional video production can either be portable or stationary. If you have a studio, you will probably have a grid on the ceiling to hang lights and would buy stationary light fixtures. Short of that, you can use portables on collapsible stands in a studio or out in the field.
An ideal portable light kit for a small professional video crew would contain at least four lights, each with its own stand and accessories. Out of the four lights, ideally you would have: One 1,000 watt with a soft box. One 750 with a soft box. One 500 watt with soft box One 250 watt with barn doors
Each light should also come with: A dimmer capable of handling that wattage A barn door Gel frames A full color spectrum pack of color gels Variety of diffusion gels and cloths Clips Sand bag weights to hold down your stands if out side Miles of tape
OK, now pack all that up in a metal case and lug it around.
Convincing beginners to use lights is not easy because it can be a lot of backbreaking manual labor. But please believe me, A FEW LIGHTS CAN MAKE ALL THE DIFFERENCE IN THE WORLD. If you don't have to march to Timbuktu dragging it all with you, it is definitely worth the effort to achieve professional results.
Here is what all those accessories listed above do:
Barn doors: Barn doors usually automatically come with a professional light fixture the same way a car comes with a steering wheel.
Barn doors are a metal accessory you attach to the front of your light. Each of the four black, adjustable doors can be folded over the light to block the light path. Barn doors are used to direct the light to where you want it to go. Barn doors are an essential tool.
Soft boxes: Soft boxes are the most glorious thing in the photographer's lighting kit if you are going to shoot lots of faces. A soft box gives you soft, diffused light directed right where you need it. A soft box is made of special cloth that both directs and diffuses the light. The sides of the box are heavy black cloth on the outside, and reflective white (or silver) on inside. This directs all the light to the front of the soft box where it passes through the thick white diffusion cloth. Soft boxes provide absolutely exquisite diffused light. However, you loose a lot of intensity in the diffusion process so a 1,000 watt lamp with a soft box is perfect for your key light.
Photographic umbrellas are another way to provide diffusion for your hot, tungsten light fixtures. Umbrellas are great if you need to provide overall, bright, diffused illumination. The hot, direct light is pointed back toward the reflective surface of the umbrella, not at the subject. The light bounces off the umbrella and gives a diffused bath of light.
The diffusion umbrellas provide is not as nice for faces as that of soft boxes. Also, soft boxes have the advantage of directing the light whereas umbrellas just bounce it everywhere. However, umbrellas can be just what you need.
Color gels: Color gels come in every hue imaginable and are a cheap, easy way for your video production lighting to take a giant leap into the professional. Color gels are flame retardant plastic sheets you place in front of your light. Lights will usually come with a collapsible metal gel holder. When lighting interviews, pale orange gels are often used on faces to give a "warm glow." Color gels are good for lighting the background and providing mood. The Halloween video is much scarier if you soak some of your lights in deep red color gels! The flowers look greener if you shine a strong, green, directional light on the leaves among all the diffused white light. Color gels are fun to play with.
Dimmers: A small dimmer capable of handling the high wattage of for each light can help you avoid hot spots in your shot. Really large crews carry an entire lighting board with multiple inputs to have individual dimming control over each light. But short of that, a few dimmers will serve you well.
Snoot: Great name for a great doo-dad. A snoot is a metal lighting accessory that directs the light to a pinprick. Snoots are PERFECT for halo backlighting. They keep the light on the hair with no unsightly spill onto the face.
Clips: Portable light kits are a wonderful exercise in setting things up and then tearing them down. To shoot a video, you often have to take over a location and pin things up here, there, and everywhere. I always found it handy to throw some cheapie wooden clothes pins in my light kit.
Adapters/Extension cords: The more portable you are, the more you have to think of all contingencies. Pack lots of doo-dads and gizmos. Two prong/three prong adapters. Miles of cables and cords. Tape. Retractable knife. Ties. Aspirin.
Natural and artificial light can be enhanced using reflectors. Anything that reflects light will work. A simple sheet of white poster board can be placed opposite of your light source to reflect back onto your subject's face and soften distracting shadows. In fact, often a fill light is nothing more than a reflector.
Even lights you buy at home improvement stores like Lowes and Home Depot can be used effectively. Point them toward the ceiling, this bounces the light, softening it, which produces a more flattering effect on the face. Plus it eliminates eye squints and grumpy on-camera people! Pointing your lights and bouncing them off the wall is the low budget method of achieving what umbrellas and soft boxes can do for you.
