It was great to have chance to provide Virtual Studio Photobooth to Vienna Boys Choir by using Chroma Key Technology. Chroma Key Technology is a visual effects/post-production technique for compositing two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video – particularly the news casting, motion picture, and video game industries. Many people, especially kids, loved playing our photobooth so much.
