Final answer:
In the 1920s, Russians and Germans utilized montage to compare and contrast images, often in propaganda and films, to emotionally affect the audience. This technique was capable of manipulating viewers' feelings by juxtaposing differing visuals.
Step-by-step explanation:
In the 1920's, Russians and Germans started using montage, or placing two things side by side for comparison or contrast, for emotional effect. This technique was particularly effective in the realm of filmmaking and propaganda. For example, Russian posters would visually juxtapose images of Stalin and Lenin to suggest continuity between their leadership and political actions. Similarly, German filmmakers of the time, involved in the expressionist movement, used montage to convey complex themes and emotions in their works. Montages could manipulate the audience's feelings by presenting contrasting visuals, such as the glorification of political leaders next to the dehumanization of perceived enemies, which would intensify the message of the propaganda.
Moreover, filmmakers like Sergei Eisenstein would use metaphoric images to craft powerful narratives. The strategic use of imagery and juxtaposition in film and posters not only informed audiences but also swayed their emotions and opinions, showcasing how visual media can serve as a potent tool for communication and manipulation.
