盛夏树荫：斑驳光影在椅面上移动

Design a park bench in the height of summer, where the subject is the light falling on it rather than the bench itself. Show the seat positioned beneath a dense broad-leaved canopy at midday, so the sun arrives only as a scatter of bright coins of light passing through gaps in the foliage — sharp-edged, roughly elliptical, unevenly distributed — thrown across the seat slats, the backrest, the paving and the legs of anyone sitting there. Detail the contrast as extreme: the lit patches blown almost to white on the pale timber while the shaded areas stay deep and cool, with very little middle tone anywhere. Show the pattern breaking and reassembling as it crosses the slats, each bright patch interrupted by the shadow gaps between boards so the light falls through onto the ground beneath in fragments. Detail the surrounding lawn as fiercely bright, bleached and slightly overexposed just past the canopy edge, making the shade read as genuinely cool by comparison. Show one person sitting with eyes closed, dappled light across their face and arms. Detail the air as still, the leaves barely moving. Set it in a mature park at noon in July. Photorealistic, high contrast, bleached white and deep green, low three-quarter view.
