Prompt

Apply the Stencil Coloring effect over a grainy black-and-white photographic base. Fill selected existing objects with bright translucent crimson, yellow, and turquoise dyes, allowing slight registration offsets, uneven dye density, and small color spills beyond their silhouettes. Leave uncolored areas monochrome with visible luminance detail. Keep the original subject and composition.

Identify

You see black-and-white moving pictures where specific objects are brightly colored. The colors often jitter or pulse slightly between frames.

Principle

Workers cut specific shapes out of a film strip to make a stencil. Dye was brushed through these holes onto a matching print.

Example

Pathé Frères: The Life and Passion of Jesus Christ, 1903.

Try it out

Watch a digitally restored stencil-colored film and track one colored object, noticing how the color edges shift slightly.

Background

In the earliest days of cinema, films were often colored by hand, frame by frame. Because this was slow and expensive, Pathé Frères industrialized the process in the 1900s. They used a pantograph machine1 to carefully trace and cut out specific areas across sequential frames. These cut frames became a stencil roll. A machine then pressed this stencil against a fresh projection print2. Velvet rollers applied dye through the cutouts onto the film below. Up to six colors could be added by using a different stencil roll for each dye.

Distinction

Hand-coloring involves painting directly onto each frame with a brush, causing wild variations. Stencil coloring applies flat dye through precise cutouts.

Aftermath

It highlights early cinema's intense labor and the desire for color long before photographic color film existed.

Question

Why did stencil-colored objects sometimes have vibrating or shifting color edges?

Show possible answer +

The stencils were cut by hand for thousands of frames. Tiny tracing errors caused the dye to slightly miss the object's outline.
