Sodium Vapor Process
A Disney traveling-matte technique that filmed actors against a bright yellow screen. Used on The Birds in 1963 and Mary Poppins in 1964, it produced cleaner mattes than blue-screen of its era.

Why it happens
A sodium-vapor lamp gives a narrow yellow light the screen reflects; a prism splits it onto a separate film strip that records a sharp silhouette used as the matte.

Image edit prompt“Make this image look like a 1963 sodium vapor matte composite: the subject is cleanly cut out and placed over a painted or photographed backdrop, with a faint warm matte halo around edges, slightly mismatched grain between layers, soft Technicolor-style saturation and gentle studio lighting. Keep the original subject and composition.”
