## Prompt final usado

Use case: photorealistic-natural.
Asset type: original photographic background for a narrow panel on a Brazilian electrical materials website, portrait image, 1024 x 1536 pixels.
Primary request: create one sober, realistic documentary photograph of an organized reinforced-concrete building construction site. This is a fictional illustrative scene and must not portray any identifiable property or specific real project.
Scene and subject: an unfinished reinforced-concrete building with clearly legible columns and floor slabs, and a recognizable tower crane in the upper half. Natural concrete texture, an orderly site, no clutter dominating the scene.
Style and camera: authentic architectural documentary photography, ground-level three-quarter perspective, natural proportions, restrained photographic treatment and realistic construction details.
Composition: vertical 2:3 frame. Keep the building structure and tower crane visually recognizable around the central and upper part of the composition so the subject remains readable in both a narrow vertical crop and a centered horizontal mobile crop. The middle and lower part will receive HTML text and a blue gradient overlay later; do not render that text or gradient in this image.
Lighting and color: soft morning daylight, a gentle pale-blue sky, natural neutral concrete tones, calm professional atmosphere.
Constraints: generate a single original image only. No people in the foreground. No text, lettering, logos, brands, signs, watermarks, frames, interface elements, or baked-in gradients.
