Green Screening which is also known as chroma keying is the use of special effects to create a set or background for a film or animation. It is a process where either two images or video streams are put together. It is done using a green sheet or blue material usually as they are colours that contrast the most with human skin tones. Any colour can be used they just have to be uniform and distinct. The important thing is to avoid using colours that are on the background material. Zu3d software allows you to take shots of visual images with a green background and import or use images from the media library on zu 3d. Green screening gives you the scope to have a background that is from fantasy or real life that would take time to make or would not be achievable with solid materials. In class a piece of green cloth was used and draped over a piece of cardboard to experience green -screening as novices. However there were creases on the green material which reflected the light and affected the chroma-keying. The video below helped me understand the process of green screening clearly.
