Apply a Wipe transition effect frozen halfway across the image, using a crisp vertical boundary between the original photograph and a warm monochrome version of the same scene. Keep spatial details precisely registered across the dividing edge, with subtle film grain throughout. Keep the original subject and composition.
Columbia references Robert Paul's 1901 film Scrooge and atransition resembling afalling theater curtain. Early wipes often required complex laboratory production. Studios were able to use them more easily in the 1930s with the advent of their own optical printers. Later films also used them deliberately for nostalgic effect, such as The Sting. The direction and shape of the boundary influence the tempo and rhythm.
Distinction
The moving edge is part of the effect; it is not an additional decorative line. Awipe indicates achange in the image space and is much more noticeable than ahard cut.
Aftermath
Aboundary in the image can itself become anarrative event.

In awipe, aspatial boundary moves; in adissolve, transparencies change across the surface.
