Canopy in Morning Mist: Structure Fades Layer by Layer in the Haze

Design an urban canopy seen at dawn in thick mist, so its depth is read through atmosphere rather than through light. Show a long repetitive structure — a row of identical slim steel frames carrying an open lattice roof — receding into the fog, the nearest frames sharp and dark, the next softer, and the furthest dissolving completely into pale grey so the eye cannot tell where the structure ends. Detail the layering as the entire subject: each successive bay a step lighter than the one before, the whole giving a strong sense of distance from an object that is otherwise plain. Show fine droplets collected along every horizontal member, beading on the lattice and occasionally falling, with the steel darkened by damp. Detail the ground as wet paving holding a soft grey reflection with no sharp edges anywhere. Show the surrounding city as almost entirely absent — only the faintest suggestion of a building mass on one side. Detail one solitary figure walking away down the length of the canopy, already half lost in the mist. Set it in an empty plaza at first light. Photorealistic, atmospheric, tonal greys, low perspective down the length.
