Filmmaking is all about illusions!

Imagine making the audience believe that your characters are actually in space. Or maybe you just trick them into believing your exterior scenes are shot using only natural light! This is part of film as an art form. However, one of the most explicit ways of cinematic deception is the use of green screens. Green screens are used in everything from backgrounds to special effects. In spite of their popularity, green screen work is one of the easiest things to get wrong in a film production!

Today we’ll talk about 5 things you should do to get better results.

Insert actors into the scene with camera work

We’ve all seen scenes with poor image compositing at least once. Scenes in which the background is obviously fake because of how flat everything seems. One of the ways in which you can avoid that effect is by not filming static shots of your characters when there’s a green screen behind them. The camera movement adds depth to the shot. If this is done correctly, it can easily pass as a real background!

Light characters to match the scene

Of course, one other thing you must always do when working with fake backgrounds is lighting your characters accordingly. Pay attention to the light sources and color temperatures of your lights. This will later be useful when recreating scenes! Illuminate your character to avoid any hard contrast that doesn’t match the lighting setup.

Use the light wrap tool on your editing software

Be conscious while your characters are in motion and how the lighting affects them. Your shot will rest in adjusting some subtle, yet significant details. Besides doing the color correction of your character and the scene overall, you can use the light wrap effect in post production. It’s important to really blend the elements in frame with the surroundings. This will give a more natural and real feel to the shot!

Take advantage of lower apertures

When using lower apertures, you are normally letting more light into the lens. You might not need to resort to the ISO so much if you are in an controlled environment. This is important because, when you are masking in post and doing all the processes required to create a great green screen effect, you want as little noise as possible in your image and you want your character’s silhouette to be as clear as it can be.

Increase the shutter speed to decrease motion blur

One of the trickiest things to achieve when using a green screen is getting a clear cutout of your elements when they are in motion. If your character is swinging his arms or brandishing a weapon, for instance, chances are that the movement of these elements turns out blurry. Shooting your scene at a higher shutter speed will capture all of your movement fluidly, leaving you with a much more defined silhouette to work with. In post, you can then work around the shutter speed effect to add motion blur back again to create a more realistic look and feel.
