In theater and film, a cyclorama (abbreviated cyc in the U.S., Canada, and the UK) is a large curtain or wall, often concave, positioned at the back of the apse.
Popular TV show The Mandolorian uses a cutting edge cyclorama to create a 3D render of the fictional planet the scene is set in,[1] allowing for actors to feel immersed while filming.
A cyclorama can be front lit or, if it is constructed of translucent and seamless material, backlit directly or indirectly with the addition of a white "bounce" drop.
A dark or black scrim, by absorbing the extraneous light which is commonly reflected off the floor of the stage can further achieve deeper colors on the cyclorama.
Lighting Designer Donald Holder uses the cyc in his work for productions of The Lion King and South Pacific, both of which he has received Tony Awards for.
