The Lastolite Panoramic Chroma Key Green Background - 2.3 x 4 Metre has a crease-free textile surface. It features a collapsible, 3-panel aluminium framework that creates a self-supporting wraparound structure. The frame snaps together with elastic contained within the framework's tubing. The fabric clips to the aluminium frame. This background system is suitable for shooting large groups for weddings, prom nights, and event photography. The frame collapses down into its own zippered case.
