When you see your favourite actor flying on the back of a monster or standing in a beautifully drawn environment in the movies or television shows, the producers likely used something called a “green screen background” to make that happen.
What is Green Screen Background?
Chroma keying is a special effects technique that involves shooting footage against a green screen and then superimposing the picture over another independently captured background. One of the most important aspects of the “chroma-key” effect is green screen technology, allowing videographers to isolate actors from their brilliant green backgrounds and then add a different backdrop in post-production.
How To Set Up A Green Screen?
Are you ready to put your green screen background to use at home? Using a green screen is as simple as following these steps:
- Prepare your Screen: Using a frame, hang your green screen so that it fills the whole backdrop of your shot. It should be as flat and wrinkle-free as possible, with no tearing or creases. The green screen should be ironed if it is foldable or folded up for storage to remove any creases or wrinkles. In order to avoid dealing with wrinkles, you may want to consider purchasing or renting a matte screen that is wrinkle-resistant.
- Proper Lighting Is Important: Many novices believe that if they have enough light on their picture, the green screen would be fine; however, in reality, you need separate lighting to illuminate your green screen background. If you don’t follow this, it will appear shaky on camera and be more difficult to identify in post-production. To prevent directed shadows, you should utilize diffused lighting that hits your screen from the top. For the best results, use two or more 1000-watt lights, diffused with a soft box or even white bedsheets.
- Ready Your Subject: A lot of distance between the subject and the green screen is desirable when filming an actor or an item. It’s hard to match the brightness of your subject to the lighting of the background; thus, this will be done later.
- Film the Video: After the green screen setup is complete, the next step is to film the scene and complete the editing properly to get your final video.
Things To Remember When Using Green Screen
- Pay Attention to the Lighting: The quality of the lighting in a green screen production may make or break the final result. For your film to be convincing, your lighting needs to be constant from one scene to the next.
- Depth of Field: The depth of focus in both foreground and background film must match; otherwise, the composite image may seem weird to the human eye and confuse viewers.
- Use A Tripod to Shoot: When using the green screen background at home, your camera must be steady and focused. An unsteady video camera in the front will contrast the background’s steadiness. Hence, consider using a tripod to keep the camera stable.
