GPT Image 2.5 Sunburst Prompt - Cuve en acier sous ciel turquoise

Photograph, 3:2 landscape, 1536x1024. A large horizontal steel pressure vessel on a multi-axle modular heavy-haul trailer, parked on an empty gravel road on open flat prairie, seen from a low three-quarter angle, camera at trailer-deck height, 35mm lens. Late afternoon, low sun from the left, clear deep teal sky that darkens toward the top, strong rim light along the top of the shell. COMPOSITION, IMPORTANT: the whole vessel is visible with empty space all around it, nothing touching or cut by the frame edges. The vessel is centred horizontally and its length fills only about 55% of the frame width. Its centre sits at about 55% of the frame height, with the horizon low, at about 75% of the height. The upper 30% of the frame is clear sky with no objects. Large calm areas of sky and ground on both sides. THE VESSEL: bare carbon steel plate shell in satin dark grey primer, fine circumferential weld seams visible, two shallow-dished 2:1 elliptical heads (not hemispherical, not round balls), two steel saddles bolted to the trailer deck with tie-down chains, one manway on top and two small nozzles, lifting lugs near the ends. Realistic scale: the vessel is about 4.5 m in diameter and 12 m long. THE TRAILER: low flat deck, many small wheels, rows of axle lines receding. No tractor unit or cab in the frame; the trailer runs out of frame at the lower left and lower right. STYLE: high contrast, bright highlights, deep shadows, restrained colour: teal sky, cool grey steel, warm dust-coloured gravel. No oversaturated orange. Cinematic, sharp, real photograph, not a render. NO people, NO text, NO logos, NO company names, NO signs, NO license plates, NO markings or numbers on the trailer, NO watermark, NO buildings, NO power lines, NO other vehicles.
