How we pick our products
Special effects appeared very shortly after the birth of cinema. In fact, the first effects were used only a couple of years after the invention of the cinematograph by the Lumière brothers. One of the pioneers of special effects is the Frenchman Georges Méliès, who went from being an illusionist to a filmmaker.
Nowadays, the technology and tools we have to create these effects are much more advanced, but many are also within everyone’s reach. In the following article, we will introduce you to the green screen, an accessory used for one of the most common techniques in the audiovisual world. Are you ready to learn more about it?

- 5 Summary
- Chroma key compositing is a technique used in film, television, and photography. It consists of recording or taking a photo on a background – generally green – before replacing the colored area with another image or video in the post-production phase.
- Green is used because it is very different from skin colors and far less common in clothing than blue. In addition, digital cameras use the Bayer filter mosaic. This means that green sensors are much more sensitive than red or blue, requiring less light to illuminate themselves and the image having less noise.
- Before you decide on a specific green screen, you will have to consider a series of critical factors. These include size, transportability, color, additional features, and naturally, the quality of the product.

You might think that the model you purchase doesn’t really matter as long as it’s green. This isn’t true.

Shopping Guide: Everything You Should Know About Green Screens
What is a green screen exactly?
From weather reporters to film directors like Peter Jackson, many turn to this very useful technique when looking to recreate fantasy environments or reduce the costs of recording in a specific place. That way, you can produce visual effects that transport us to unknown worlds and create a lot of fun optical illusions.
Why is the screen green?
There are twice as many green sensors as red or blue, so they are much more sensitive and require less light. In other words, the green channel of the camera has less noise due to the higher sensitivity of the sensors. Keep in mind that this is a specific shade of green.
Besides, the blue matches the color of the sky, which makes the task a little more complicated if we want to record outdoors. However, the blue screen is necessary to record at night or with a very dark image. Ultimately, green and blue are the most common colors because they are the most different from skin colors.
|Green screen||Blue screen|
|Price||More affordable||More expensive|
|Use||It is the most common.||It is generally used for night videos and when there are green objects.|
|Skin pigmentation||Rare||Very rare|
|Effect||Digital cameras are more sensitive to the green color (just like the human eye).||It is the color of the sky, so it can produce reflections.|
How do I get the most out of my green screen?
- Pay attention to the lighting: It should be as uniform and constant as possible to make the post-production work easier. You are advised to record in an environment where you can control the lighting.
- Indoor recording: Place two spotlights on either side at a 45-degree angle and mid-height from the green screen.
- Outdoor recording: Try to record at a time of day when the light is uniform.
- The subject and the green screen are illuminated separately: The subject being recorded should be at least 6 feet away from the screen (the more, the better) to prevent color contamination in the subject and to avoid shadows. Always illuminate the actor according to the background image.
- No wrinkles: make sure there are no wrinkles on the green screen. The fabric has a tendency to wrinkle, so you may have to use tweezers.
- Be careful when using the same colors: As you can imagine, your actor should be dressed in green if you use this screen. Avoid green objects as well.
- Avoid materials that reflect: these include glass and metals. You should also avoid very light colors like white.
- ISO: Set the lowest sensitivity you have on your camera to reduce image noise and make the screen work better. You will end up with a cleaner image.
- Color temperature: The color temperature of your camera has to match that of the lights you are using. You can use a photometer or the camera’s own exposure tools to measure the light intensity.
- A good focus: It is important to keep the actor or object well-focused so that the edges are more defined, and it is easier to cut out of the green screen.
- You can now proceed with your recording or photo session!
- The final touch: During post-production, you will use an editing program to replace the green (or blue) area with the desired image.
What type of green screen should I get?
Regarding the installation of your green screen, remember that you must have a way to hang your screen if you decide to opt for a model without support. In addition, we encourage you to choose an easily transported screen if you need to work in different places. We will delve deeper into this criterion in the final section of our guide.
What is muslin?
Well, well, well! Now that you know the basics about this audiovisual accessory, let’s go over some of the aspects that you should consider before you get your own green screen and put your creativity to use. The following criteria will help you choose the model that best suits your tastes and projects:
Size matters, both for the type of project you want to carry out and for the space available to you. As you noticed from our selection, most models on the market will measure up to 9 x 15 feet, with some exceptions. Before you make your purchase, check that the dimensions of the green screen you are interested in actually fit the type of project you want to work on.
In the same vein, you should pay attention to the size if you are looking to create your own small set at home. If you have enough space, you should easily extend the green screen without problems. Don’t forget to follow the recommendations we have given you earlier regarding the distances necessary to obtain optimal results.
You have to analyze everything you need to make your ideas become a reality. You may not need anything but the fabric because you already have a support, and someone is lending you the lights. That way, the green color will be more than enough. In that case, go for the most basic option – as long as the size is right, of course.
If you are looking to set up your own little studio, on the other hand, you will probably want to go for something more professional. You have the possibility of acquiring a whole set that includes support, lights, various colors, and more. By having everything you need at your fingertips, you can let your imagination run free.
This is a crucial factor when it comes to buying your green screen. Think about where you want to record and do photo sessions. As you have seen earlier, some models are much more portable than others; fast and easy to deploy is exactly what you’ll want. All the models of our selection can be transported, but some are harder to put together than others.
If you have set up your little set in a specific place and don’t intend on moving from there, you won’t necessarily have to look for a model whose main characteristics are lightness and ease of transport. The final decision is yours, but making an informed one is always the best solution.

You naturally have to choose the color of your screen, too. While this article focuses on green screens, we have also discussed the possibility of doing chroma key compositing with other colors.
As we mentioned earlier, you will also find blue screens – the second most common color for this technique. Others include gray, white, and black, which can also be very useful in specific contexts. Choose the color or colors you need based on your projects.
You can’t judge a book by its cover. In fact, we don’t recommend purchasing a product without first reading the opinions of past users. You can generally find useful information in these reviews, and the overall rating of the green screen can give you a good idea of its quality.
In addition, you can find dozens of forums on film or photography that have discussions on green screens or how to create different effects. We encourage you to make the most of the incredible online library.
