Top 4 Tips to Use a Green Screen

A green screen is one of the most used backdrops for filming. In this, the footage was then superimposed onto a different background by video editors. The process of this visual effect is known as the Chroma key. It’s also known as color keying, Chroma key compositing, or simply keying. 

Green screen technology is the most important part of the Chroma key effect. This allows video editors to differentiate the subject from the green screen background and then apply a separate background in place of the green screen. Here are the top 4 tips to use a green screen. 

Consider the Lighting

This is one of the most important tips you need to remember while using screen technology. If the green screen is not made of solid color, the Chroma key software will face challenges to distinguish the lighter green from the darker ones. While lighting your green screen backdrop, make sure the light is even. Pay close attention to notice if soft lighting is falling on the entire surface of the green screen. This is extremely important for perfect keying. Many filmmakers neglect to consider the lighting of the green screen background and focus only on lighting the subject. Despite the placement, make sure the green screen is properly exposed to the lights. 

Make Sure the Subject Wears Contrasting Colors

It doesn’t matter which type of colored outfit you choose for the subject, make sure they don’t wear green as it will make them blend with the background. Therefore, the Chroma key will make the green screen background and the green outfits disappear. Make sure the subject wears colors that are on another side of the color wheel. This way you can avoid any mistakes while editing. 

However, you can purposely wear a green outfit if you want to replace some portion of your body with VFX. This is how Hollywood films monsters. 

Use Low Aperture

The camera quality is another important thing for the green screen background. When you open the aperture of the camera, you will notice a lower F-stop number. The lower the camera’s F-stop, the better the depth of field. Remember that several factors will differentiate your subject from the background. If you apply a sharp focus on your subject, the green screen background will appear softer. On the other hand, a soft focus on the subject will make the green screen blend. Therefore, make sure the focus on the subject is sharp. 

Consider High Shutter Speed

Implementing the high shutter speed of your professional camera will help you prevent motion blurring problems during the shooting session. As per Adobe, the shutter speed will determine the amount of light that goes into the lens. For example, if you’re filming a news broadcast and your subject isn’t moving, then make sure the shutter speed of the camera is double the frame rate. If you’re shooting the video at 24 FPS, the shutter speed should be 1/48. On the other hand, if you’re shooting an action film and there are a lot of movements in front of your green screen, make sure the shutter speed of your camera is higher. However, keeping the shutter speed too high will affect the exposure.
