Visionary photomontage are grayscale photos from the past edited to look like a scene from the future with a colorful technology of the future. Image sources are found in online repositories and archives, requiring to imagine possibilities of localized futuring. It is possible to use image generation AI such as DALL-E and Craiyon to produce visionary photomontages.
Visionary photomontages are a typical feature of speculative design mockumentaries.
