The students learned about chroma keying, the process of editing out the background of a photo or video which uses a single color background and then superimposing it together with another. Usually the background color is either blue or green because it is the most different from the hue of skin color. Because many people use a green screen as a backdrop, the process is sometimes referred to as "Green Screening". The students also learned some tips on taking a good Green Screen photo to ensure cleaner editing (good lighting, eliminating shadows and wrinkles in the fabric, and not wearing green). Then the students picked out their background images and tried to imagine how they would appear in it. Then we setup a green screen and took some photos of the students posing.
