The Savage 10 x 20 ft. Infinity Lint Free Pro Cloth Background (ProChroma Green) is crafted from extra durable, 100% cotton material that makes it a top pick for heavy-duty work such as large product shots and rugged location shots. Pro Cloth is a must for images requiring clean, clear backgrounds and is ideal for working with colored gels. Like all of our muslins, Pro Cloth's matte finish does away with reflections. Savage ProChroma Infinity Pro Cloth is a true chroma key green and is ideal for both still and film chroma key work.
