Final answer:
The superimposition of two images to make a single composite image is known as double exposure, where the overlapping of images can suggest thematic connections or contrasts.
Step-by-step explanation:
The technique described in the student's question involves the superimposition of two images to create a single composite image. This technique is known as double exposure. In filmmaking and photography, double exposure is used to convey complex ideas by laying one image over another, thereby creating a juxtaposition that can prompt the viewer to establish a relationship between the two elements. The overlay can be used to suggest a thematic connection, draw a contrast, or highlight a narrative element. For instance, placing an image of a soldier over a scene of political debate might suggest commentary on the relationship between personal sacrifice and political decision-making. This technique can lead to memorable imagery and provoke thought, as seen in the way documentary filmmaker Ken Burns uses juxtaposition to engage viewers with historical narratives.
Other terms mentioned but not related to the concept described include: cross-cutting, which refers to alternating shots from two sequences to suggest they are happening simultaneously; freeze frame, where the motion picture is halted to create a still image; and smash cut, a sudden transition between scenes that is abrupt and often used to startle the audience.
