Learning how to evenly light your green screen backdrop will give you better results when it comes time to edit your video.
Lighting a green screen is fairly simple from a technical perspective, yet many DPs who don’t have much experience with chroma key work are prone to making some unfortunate mistakes on set. Unlike traditional film lighting, which is all about finding contrast and mood by balancing light and shadows, lighting a green screen is all about evenness and consistency.
For the purpose of this post, I’ll describe a basic green screen lighting setup that involves only two background lights. While two lights might be all you need for many scenarios (such as an interview setup), keep in mind that the basic principles outlined here can be applied to wider and larger green screen setups too — you just may need to add more light.
This image is inconsistently lit. The editor will have a difficult time keying the darker edges of the frame.
The most crucial thing to remember when lighting your green screen: any area of the backdrop that appears in the frame must be lit perfectly even and exposed correctly. If your backdrop is lit properly on one side but underexposed on the other, your compositor or editor will have a very tough time pulling a clean key. The same applies to a backdrop that’s either over or underexposed. Any attempt to pull a key from a backdrop that isn’t actually reading as green on camera will inevitably be a failure.
Lighting Green Screen Backdrops
The key is the same for achieving soft light in any other shooting scenario — use big, soft light sources. If you point a hard light source (such as tungsten light with no diffusion) at your green screen, you’re going to run into trouble. The light will have a hot spot and there will be a gradient surrounding it, ultimately giving you an uneven light to work with.
Conversely, if you were to point a tungsten light (let’s say a 2K source) at the green screen, but use a large 8 x 8 frame with a silk to diffuse the light, you’ll be in great shape. Personally, I prefer to use double diffusion when shooting on a green screen. My ideal setup typically involves a bright light source that’s first diffused by a standard 4 x 4 silk on a C-stand, and another 8 x 8 frame in front of that silk for an additional layer of diffusion. This ensures that the light is as even and soft as possible.
Placing Green Screen Lights
Assuming your needs are relatively simple, you can use a minimum of two lights to illuminate your backdrop. Using the setup described above, I recommend placing one light (with diffusion) on either side of the greenscreen, a few feet back on a 45 degree angle.
Right off the bat your results should be pretty close, and you can fine tune/adjust the angle of each light to make sure they’re not overlapping too much in the center. In other words, you don’t want to have a hotspot in the middle of your frame if both lights are spilling into each other. Be sure to adjust your lights and use flags when necessary, so your lighting is as even as possible.
It should also go without saying that you’ll want to use the exact same lights on either side of the green screen for the sake of consistency. If you’re using two different lights, you could run into exposure issues (or even worse, color temperature issues) which could once again cause headaches in post. With regards to the rest of your lighting setup, these will be creative decisions and are ultimately up to you.
If you want a more dramatic look on your talent, Origin driver download. you can light them from the side. Alternatively, you might use two more flood lights on the talent’s face to create an even flat light. No matter what creative look you’re aiming for, the green screen will always need to be lit the exact same way.
On bigger productions, you may need to use overhead lighting, additional sources, or more diffusion, but the basic principles outlined here will apply no matter what.

Light sensitivity and glare are common problems for people with glaucoma. Patients who experience light sensitivity typically feel discomfort from sunlight, incandescent light and/or fluorescent lights. Halogen lights, like those used in car headlights and fluourescent lighting or fixtures can cause an uncomfortable glare for those with glaucoma. Here are some tips for driving and working at your computer – two scenarios impacted by glare and light sensitivity
DRIVING WITH GLAUCOMA
Many glaucoma patients choose to avoid night driving due to the headlight glare that makes is difficult to see well. Warning signs that driving may be dangerous include: loss of peripheral vision (making it difficult to see and react in time to avoid obstacles like other cars and pedestrians coming from the side); blurred vision (making it harder to distinguish clear images and see movement such as passing cars or someone crossing the street); increased light sensitivity, (making it more difficult for your eyes to adjust from headlight glare at night); and close calls (because of a failure to notice obstacles in the road).
Here are two resources that can help you evaluate your driving skills.

If you choose to continue to drive be sure to:
- Select proper glasses for both day and night driving. Darkened or polarized lenses can be helpful in blocking glare in daytime driving or during outdoor activities like fishing, skiing or riding a bike. But when driving at night, the eyes need to adapt to darker natural conditions. If you wear glasses, keep them clean.
- Avoid wide-temple frames, which can interfere with side vision.
- When you buy a car, choose a clear windshield and keep your windshield clean, inside and out. People often forget the importance of wiping off the inside of the windshield, which is easily smudged.
- Maintain and clean off your headlights, which can get coated with road grime.
- Make sure your windshield wipers are in good condition and change them as needed.
- Keep pace with the flow of traffic.
- Be alert. Keep eyes on the road ahead but check each side of the car for vehicles, children, animals or other hazards. Move your head and eyes frequently from side to side and glance often at the rear view, side mirror and instrument panel.
WORKING AT YOUR COMPUTER
Screen Lights Up But No Display
Extended time on the computer jeopardizes even the healthiest of eyes. This is magnified for people with glaucoma. A few tips might help.
Light On Laptop Screen
- Glare problems can be reduced with a good filter that fits over your screen.
- Before selecting a permanent position for your computer, check out the effect of light on the screen. Avoid facing the window. Light streaming from outside creates glare and interferes with your view of the screen. Light from a window behind you may also worsen glare.
- Overhead lighting may also produce glare. Try illuminating your screen with desktop lighting, focused directly on your work.
- Arrange your monitor in such a way that you gaze down at a 15 degree angle, which is easier on your eyes.
- Avoid staring at your screen – Look around, e.g. out of a window or at a far wall. And remember to blink. Not blinking can promote dry eyes.
