Green Screen Systems Virtual Sets Portable Lights WithEspecially now, with digital video cameras that allow you to adjust and set a custom white balance, you can use a less-expensive solutionshooting your scene outdoors, using hardware-store lighting, or even building your own portable lights with foam core, duct tape, hot glue and compact fluorescent bulbs.
Green Screen Systems Virtual Sets Plus One LoneFor example, this image was shot with three of these homemade lights (Softbox with foamcore reflector, and two portable clamp lights youll see below, plus one lone hairrim light bulb) against photo-green paper on a wall. Sure, you may be able to get away with some of these crude basics, especially with todays digital cameras that let you set the white balance to adjust for off-color temperature lighting. But when it comes to shooting green screen, the fewer corners you cut, the better. That still doesnt mean that you have to buy or rent expensive lighting gear to get a good, useable result. Green Screen Systems Virtual Sets Professional Studio LightingThe compact fluorescent bulbs will cost you a bit more, depending on the quality you use, but this is by far the best alternative to professional studio lighting that Ive seen to date. As you can see in this image, the plug-in dimmer is an option I chose to control my lights, but it only works with the more expensive dimmable bulbs. You cant find these easily at the hardware store, so if you want optimum color temperatures that are closest to daylight (such as the 5100K dimmable bulbs I used here), youll have to find a professional online lighting source. At 75-watt light output per bulb, giving me a 450-watt output fixture, thats still a very reasonable price when you consider the alternative of having to buy expensive cool-lighting fixtures and tubes like Kino Flos, or renting lights for a single day. You should aim for daylight or as close to 6000k-6500k as possible, but be sure all your bulbs match color temperature You can also unscrew a couple of bulbs to diminish the light output of your fixture as needed, if you choose not to use the more expensive dimmable bulbs. I used white duct tape on the inside surfaces to give the light a clean, professional look while maximizing the reflective white space. I also used more hot glue and Velcro than the original plan called for, because I wanted a sturdy and durable design. I used more black duct tape over the heavily glued tabs shown here, to make the light look better and be more durable. In this image, youll notice the pole attached to the back of the foamcore lightbox, per Victors instructions to allow you to secure it with clamps vertically to a stand or suspended from a boom extension. The lights can be on for hours and still stay cool, which is a big advantage over the old-style hot lamps still used in many studios today. The light can easily be collapsed for transport or storage - the screen comes out; then, you remove the bulbs and put them back in their original boxes for safekeeping. You remove the Velcro tabs, collapse the sides of the box, and fasten them together with Velcro tabs. By using some simple components from the hardware store and some green fluorescent bulbs to enhance my green screen backdrop (and use much less light to get the coverage I needed), I was able to put together light fixtures for less than 20 each. Below, you can see that I started with a couple of the green fluorescent bulbs screwed into a T and then attached to a socket plug. I put two of these into a power strip that I glued to the inside of the fixture. Because each of these bulbs draws only 24 watts (but has a 100-watt output), there is no danger of overloading the power strip: youre getting about 400 watts of light with less than a 100-watt draw.
