What is a green screen and how does it work?
The green screen is an accessory needed for the chroma key compositing technique, which is widely used in the audiovisual world. It consists of recording on a background of a specific color (usually green or blue), before replacing that colored area with another image or video in the post-production phase. Editing programs are required for this last stage.
From weather reporters to film directors, 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 viewers to unknown worlds and create a lot of fun optical illusions.
What types of green screens are there?
In addition to the traditional green screens, blue screens are the more expensive counterpart and are generally used for night videos or when there are other green objects present in the shot. Skin pigmentations appear very rarely.
There is a slight disadvantage of the digital effect as the screen has the color of the sky, which might lead to reflection production.
Shopping Criteria for Green Screens
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 on which you’re working.
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 could 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 (if you already have a support beam and lights). In this case, 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. Acquire a whole set that includes supports, lights, various screen colors, etc. With 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; you’ll want something that’s fast and easy to deploy. All the models of our selection can be transported, but some are harder to put together than others.
If you have set up your 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 portability. 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 project.
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. We are confident that you will find people who have similar projects to yours, and their opinion and experience can help you choose between various models.

Why is the screen green?
Nowadays, green is the most common color, but black, white, blue, and more have are also used for this technique. Originally, blue was the most popular; the main reason why green has replaced it is that the latter is a more common color in clothing, such as jeans, or eye color. In addition, it is more expensive.
There are twice as many green sensors in a camera as there are 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 only true for 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.
How do I get the most out of my green screen?
If you are not an audiovisual professional but want to make your way into this world, or if you simply want to have fun, here is a series of tips to improve the quality of your results when using a green screen.
- Pay attention to the lighting: It should be as uniform as possible to make post-production 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 across the screen.
- The subject and the green screen should be separately illuminated: The subject being recorded should be at least six 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: Muslin has a tendency to wrinkle; be sure there are no wrinkles on the green screen when it comes time to record.
- Be careful when using the same colors: As you can imagine, your actor should not be dressed in green if you use this screen. Avoid green objects as well.
- Avoid materials that reflect light: These include glass and metal. 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; this way, 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.
- Good focus: It is important to keep the actor or object in focus 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?
There are several factors to consider for this. Think about the size you would like your green screen to offer, and whether or not it is sufficient for what you want to do. The models that we have selected in this article do not exceed 9 x 15 feet, which is generally enough for most things.
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 portable screen if you need to work in different places.
