Dos and Don’ts: 7 Important Tips for Using a Green Screen

What is a Green Screen?

A green screen is a blank green background that can be used to change the background image and/or create special effects by adding images to replace the green background. Green screen technology has become a staple in the film industry. It allows filmmakers to change the background of any subject to virtually any background or setting they want. However, using green screens requires skill and attention to detail to achieve the desired results. Here are some dos and don’ts to keep in mind when using a green screen in your filmmaking:


Do make sure to properly light your green screen by keeping the lighting even and avoiding shadows.

Don’t light your green screen with uneven or harsh lighting as it can cause hotspots and shadows that are difficult to remove in post-production.

Green Screen Material

Do use a high-quality green screen material and ensure it is wrinkle-free or use green paint.

Don’t use green screen material that is poorly stretched or wrinkled since it can cause unwanted shadows or distortions in your footage.


Do make sure the subjects are a safe distance away from the green screen.

Don’t position your subjects too close to the green screen as it can cause unwanted reflections or green spills on your subject.

Do consider using grids or tracking markers to help with post-production compositing and alignment.

Don’t move the camera or green screen during filming as it can cause alignment issues which may make it difficult to composite your footage in post-production.

Do pay attention to the edges of your subjects and avoid clipping or fringing in your final composite.

Don’t forget to pay attention to the direction of light and ensure that the shadows match both the foreground and background elements.


Don’t rely solely on green screen technology to create your entire environment or setting. Use practical effects and physical sets when possible to create a more realistic and cohesive look.

Do use a high-quality camera to capture as much detail in your footage as possible.


Do use professional editing software and pay attention to details such as shadows and color grading.

Don’t rush through the post-production/editing process. Make sure you take your time to ensure that your composites are seamless so that the final product looks professional.
