As mentioned prior, most digital cameras capture more information on the green channel. Let’s start with the pros for using a green screen. Let’s explore the pros and cons of green screens vs blue screens. In most cases, a green screen will serve you better. Well, the reality is that everything is project dependent. So the answer is clear, right? Green screens are superior to blue screens. Bright green is also a much less common color in costumes and wardrobe, creating fewer problems in post. Requiring less light means it’s cheaper to use.

Green screens also require less light than blue screens because green reflects more light - again, because it has a brighter luminance. This is because the green channel is also used for luminance, which, in turn, makes green easier to key out in post-production. For one, most digital cameras capture twice as much green information as they do for red or blue colors. Several factors contributed to this, included the growing popularity of digital cameras. When movies began shifting to a digital post-production process, it brought on the rise of the green screen.

Let’s start by defining chroma key compositing and looking at why we use blue or green in the first place.

If you’re looking to implement a green screen (or a blue screen) in your next project, check out our guide to green screen for every detail you need to know. a green screen? The answer is yes, and you’ll find out why in this article. But is there any real difference between using a blue screen vs. Just as filmmaking and cameras have advanced over the years, so has the use of blue screens and green screens.
