The Caruba Background Cloth 2x3m Chroma Key Green is made of excellent quality non-woven cotton. The chroma green colour makes the fabric ideal for chromakey purposes for photo and video. You can use the cloth for live blogs where you simply fill in the background with software, but you can also use it for photography where you place the subject in a different environment with the help of, for example, Adobe Photoshop. At the top of the cloth there is an eight-centimetre zoom where the cross beam of the background system can easily slid through.
