Green Screen is a technology used in video editing to replace one image with another image. The technique is called Chroma Key. You will need a green sheet or screen, webcam, lights, and video editing software. For your set up to work effectively it is important to have good lighting. The best and safest is florescent lighting. It is important the lighting is even. Any digital camera will work as long as it can download digital images and video. It is best not to zoom in when you take photos and videos. The better the camera the better It will look. Tosh.O is a good example of someone who used the green screen on TV. A lot of movies use the green screen as well. The group showed a very imformative video on how movie producers use green screen in movies. Actors gave interviews on how hard it is to act like you are someone you really aren’t. You can use blue or green screens because those pigments are not in the human skin color. Some film producers mentioned they don’t like to use green screen becuae of how boring it is to film in an empty room. You have to really use your imagination when using the green screen. Why the color green? Green is used the most because digital scensors are more sensitive to that color. It is also easier to delete the backgounf of green because it doesn’t interferr with human skin tones. Green is also said to complement skin better. When using the green screen softwaire, keying out, means if makes anything green transparent. People can use green sheets that you can find cheap at the store. You want a jack on the back of the camera you use so you can plug in an external microphone. You can use the green screen in the classroom by using the app Green Screen by Do Ink. The app is $2.99. It is super simple and easy to use. You click on add, create a new project, and it will pull up options to take photos, videos, or upload. You can upload whatever background you want to be in and upload a photo of yourself in front of the green screen. The app will delete all the app and layer the two photos on top of each other. It will now look like you are anywhere in the world. There are serveral apps available and more complex but that app is user friendly for students. On some more advanced apps, you can use videos. One way to use the green screen is to create character, put them on green sticks, and have the students retell stories in front of the green screen and pick out their own backgrounds. Another great way to incorporate it in history is to summarize a war or anything in front of the green screen and put background images from that war or time in history. You can also do book talks in front of the green screen and select a backdrop that matches the book. This will get students engaged and wanting to read the book!
