Wan2.7-Image Worldbuilding Concept Art: An Atmospheric Visual Exploration

Taking "worldbuilding concept art" as the goal, this is an atmosphere-oriented visual exploration using wan2.7-image-standard. The workflow starts with a single reference image (the spatial skeleton of old-city ruins) as the anchor for composition and perspective, then redraws it with a mixed Chinese-English prompt into another worldbuilding setting for the same scene—lowered horizon, layered fog pulled apart, distant skyline forming a scale contrast with a colossal structure, and a locked unified cold gray-blue palette to keep the output from sliding toward homogeneous "AI standard face" aesthetics. This is an image-editing/reference-fusion use case: the schema's image_urls accepts up to 9 reference images, but this piece passes in only 1 to keep the composition controllable; once a reference image is passed in, the output aspect ratio follows the reference, so the aspect_ratio parameter is no longer relied upon. resolution is fixed at 2K (the resolution ceiling for standard text-to-image and editing is 2K), and seed is fixed for reproducibility and iteration. Applicable scenarios: concept validation for film/game pre-production art, single-frame extrapolation for worldbuilding mood boards, rapid A/B comparison of different settings within the same space, and batch production of serialized concept art requiring stable color palettes. Developers can directly reuse this input structure and expand image_urls to multiple references for multi-image fusion.
