Handschiegl / DeMille-Wyckoff / Wyckoff Process
Similar to stenciling, the Handschiegl process was applied mechanically to manually defined image parts. Therefore it is an applied color process.
After the film was shot and edited, for each color applied a separate print was made. In contrast to stenciling, the image parts which were to be colored were covered with an opaque paint. Subsequently a dupe-negative was made. A tanning developer hardened the gelatin in the exposed areas while leaving the blocked-out areas soft. The softer parts absorbed the acid dyes which were then transferred onto the positive print during an imbibition process. Usually up to three colors were applied to a film. The process allowed for subtle blending of different colors.
