A green screen is used as a backdrop in chroma key photography, which is a process that replaces a solid-colored background from behind the subject of a photo (or video) with a new background. Whenever you watch the weather forecaster on TV standing in front of a map, or Spiderman climbing down a building, you are seeing chroma key photography at work!
You may be wondering, “Why use a green screen?” Because separating a background from a human subject in a photo or video is much easier if the background is made of a solid color which is not found in human skin tones.
Green screen backdrops can be purchased from our online store. The green screen’s we offer are pillow case style backdrops. They work with the frame we sell. The benefit of using a pillow case style green screen is that the material is stretched really tight over the backdrop to give a smooth surface. This is optimal for taking photos with the photo booth.
Lighting is crucial when green screening as the better lit a shot is, the easier it is for the software to separate the greens from everything else. External light sources (typically tripod based photography fill lights) must be used to neutralize people’s shadows that land on the green screen canvas.
The person in the photo should usually be about 4 ft away from the backdrop. If closer, potential splash pixelation canoccur when the flash fires, re sulting in a green hue of jagged pixels showing in the finished photo.
Be aware that any people wearing green in these pictures will have that portion of their body replaced by the green screen background.
