WHAT YOU NEED:
A large piece of green fabric or a large plastic green table cloth (I got mine at the dollar store)
- An app. My favorite is Green Screen by Do Ink. It’s free and I get zero benefit by suggesting this to you. Just search “green screen” or “chroma key” in your app store. You need something that will key in real time. You do not want an app that will let you key images after you have recorded a video. That’s why the app with the octopus logo is my favorite.
WHAT TO DO:
Hang up your “green screen”. Try to get any wrinkles out by steaming it and stretching it tight. Make sure you hang it in a well lit area to avoid shadows. Remember, your maps will only show up where the green is, so make it as large as you can. For example, if you want to be able to see your feet in the shot, the green fabric will need to go all the way down to the floor.
Set up your phone or tablet with the screen facing your green if possible. Some apps cannot use the forward facing camera, only the back.
- Find the pictures you want to show in your weather report.
HOW IT WORKS:
Anywhere our TV camera and your phone camera sees the color green, it will put your pictures or my weather maps. Watch this video from our TV studio to see how it works in real time!
Meteorologist Hannah Strong demonstrates how the green chroma key screen allows our meteorologists to present the weather forecast every day from our studio.
This is why you rarely see Meteorologists wearing green because the weather map would show up on that green piece of clothing.
DISCUSSION IDEAS:
Would another color work instead of green?
