It is one of the most exciting things in movies to see collapsing buildings or dragons flying through the sky.You can use a green screen to achieve this in your videos.When using a green screen, lighting it properly is the most important thing.If you know how to prepare your equipment, position your lights and subject, and expose your green screen properly, you will be able to create your own amazing background.
Step 1: There are flaws in the green screen material.
When light is shone on the green screen, it can make it harder to capture a smooth and even color.If the fabric is wrinkled, steam or iron it until it is smooth again.If the fabric is still bunching, stretch it out tighter.If you are using paint, check for areas that have been damaged.The entire surface should be re-painted if there are a lot of damaged areas.
Step 2: There should be no reflective material in the room.
Light bouncing around the room can make it difficult to pick out a solid color for the green screen.Black drapes should be hung around the room to stop the light from bouncing.
Step 3: Make sure your camera shoots in a format compatible with your computer.
It is not a good idea to film an entire scene and then not be able to export it to your computer for editing.It's a good idea to check your camera before you start shooting.If you want to get a higher-quality image, you should use a file format that preserves all the small details of your video file.
Step 4: Make sure your lights are the same type.
Different lights have different color temperatures.You should use the same lights to light the green screen.
Step 5: The green screen has a light on it.
To angle the lights at 45 degrees, keep them a few feet away from the green screen.If you place a light in front of the green screen, it will cause a hotspot or an area where light is more concentrated.If your screen is large and the lights on the side can't reach all of it, place two lights at the bottom of the green screen pointing up.If you want to adjust the lights on the green screen, start with this basic setup.
Step 6: All areas of the green screen are lit.
If there are any shadows or areas that the light hasn't reached, take a step back.It's important to see one consistent color.If you use too many lights, the amount being reflected back or spilled onto your subject will increase.It will be harder to separate your subject from the green screen in editing.
Step 7: Your subject should be far away from the screen.
The amount of light reflected onto them from the green screen will be reduced.5 to 10 feet is a good distance.The subject should be positioned as far away from the green screen as possible.If your subject is standing on the green screen, place a mat underneath them to prevent light from hitting them.
Step 8: Use a key light to light your subject.
The main light is the key light.Consider where the light will come from when placing it.Make sure the key light is a few feet higher than the subject.Don't light your green screen and subject at the same time.Light your subject separately to reduce shadows.
Step 9: There is a fill light next to the key light.
The fill light is weaker than the key light.Place the fill light on the other side of the key light and adjust it until there are no shadows on your subject.The key light should be softer than the fill light.You can lower the intensity of the fill light by taping a wax paper over the lens.
Step 10: There is a backlight behind the subject.
The halo effect around the subject will be created by the backlight.This will make your subject look bigger.
Step 11: You can check the exposure by looking at your camera monitor.
Exposure is the amount of light the camera is taking in.If you want to capture colors other than green, you should aim for a little less brightness.It's better to look at the camera monitor than it is to use a waveform monitor.If you don't have a monitor, you can download a app on your phone.The evenness and exposure of your lighting can be checked by these apps.
Step 12: To get the correct exposure, adjust your camera's aperture.
Light can enter the camera through the hole in the lens.The green screen should be widened if it's underexposed or too dark.If it is too bright, close it.
Step 13: To reduce noise, lower your ISO.
Random specks of color can appear in your video or photo.ISO is a camera setting that lightens a picture, so higher ISOs may lead to more noise, which can make it harder to separate a single color for your green screen.This may underexpose your green screen if you lower your ISO too much.Make sure that your camera's ISO settings don't make the picture too dark.
Step 14: As needed, add or remove lights.
Adding or removing lights to lighten or dim the green screen is a way to correct exposure problems.If your lights are too bright, you can make them softer by taping a diffuser over the lens.
