What makes style recognizable
You need simple shapes, clean colors, vintage technology and optimistic science fiction. If you add too much neon, the result will go to cyberpunk; if film and household parts - in the 90s.
It is better to keep retrofuturism separate from the 90s: vintage technology, optimistic science fiction and an image of the future from past are important here.
What to include in the prompt
- vintage sci-fi scene or portrait
- chrome, rockets, analog panels, soft light
- Do not mix with cyberpunk and modern logos
How to get a reliable result for retrofuturism
Start with one clear source image and one main change. Name the face, object, angle or color that must remain unchanged.
For a complex idea, split the work into steps and compare the first result before launching a full series.
