Now, choose a background and the program will ask you to step out of the picture. (Kind of looks like the intro to the Brady Bunch without all of the actors looking at each other within the matrix.) You should now see your face via the webcam in the middle “normal” shot and some backgrounds all around you. You want to select the second to last square under your shot effects.
To access the green screen effects in Photo Booth launch the application and click on effects on the bottom right of the window. Photo Booth has green screen effects backgrounds, although you don’t actually have to have a green screen, but a solid background seems to work the best. Mac computers come with two programs that you can use green screen effects with pretty easily. (Just a note: there are also blue screen effects, which is virtually the same thing but uses the color blue in the background instead of green.) For example, any time you watch the weather report on the news, they are using a green screen effect to broadcast the Doppler Radar behind the weather person. What is green screen effects? Basically the green screen effect is used to replace a chroma key green background and replace it with another video or still picture. Partly because of its ease of use, and partly because it speeds up the process of set design, or eliminates it all together. Green screen effects have been a growing trend in education in the past few districts that I have worked in.
