Marine Filming tank

Green Screen

Square Sail is now able to provide a green screen facility at Charlestown’s marine film tank.  The provision of the green screen backgrounds will further expand the range and scope of filming that can be carried at the harbour, with Productions able to shoot any type of water based scene, day or night within the controlled marine tank environment.

Our stock of chroma key fabric can be used on frames, scaffold constructions or as drapes, making it suitable for any area, large or small.
