Prompt d’image
PRIORITY SOURCE-SPECIFIC GEOMETRY AND EXPOSURE: A radically modified widebody LONGTAIL RACING coupe based on vintage911, not a stock street911. Rear left terminates in a very broad dark nearly featureless recessed opening rather than a recognizable stock taillight bar and bumper; rear wing is a long flat angular silver horizontal plane extending over the opening at left. Keep low roof and elongated horizontal race body. Compact polished disc wheels, body close to ground. Shift whole car down: roof47% frame height, contact baseline73%, no car geometry above47% except thin highlight streaks. Camera angle is only slightly behind a side view, reveal more side than rear. The hill is a fine velvet-like vegetation texture crushed into a single nearly black band between22% and56%, not a sunlit rocky hillside. Ground is very fine smooth matte dusty taupe with sparse subtle grit, not high-contrast coarse gravel. Sky is dark desaturated slate gray-blue. Optical glints form overlapping clusters of many fine rays and long thin vertical diffraction spikes around the left wing and roof, not isolated evenly spaced decorative four-point stars. Overall photograph is underexposed, with brilliant chrome highlights against very dark middle-distance shadows.
Vertical 3:4 editorial automotive photograph with restrained analog film color and extremely bright optical star-filter glints. A single low wide classic 1970s Porsche 911 based racing coupe, mirror-polished chrome body, parked on flat dusty taupe gravel, seen in rear three-quarter view from its left rear side. Car points toward the right. Camera is low at roughly wheel-hub height, normal to short-telephoto perspective, no wide-angle stretch. The entire principal car body extends from x1% to x98%, the rear wing begins near y50%, roof top at y47%, and tire contact at y73%. Leave the upper 45% for the landscape and the lowest 26% as uninterrupted dusty ground. Rear left black opening sits at x3–28%, y58–66%. Broad angular silver rear wing across the left third; round roof and blacked-out side windows span x25–73%, y47–57%; front nose at x97%, y64%. Near rear wheel centered x51%, y66%, front wheel centered x88%, y65%, with black tires and bright polished flat disc-like hubcaps. Low wide side skirt and flared rear arches. No occupants visible.
Landscape geometry: a gently rising dark brown scrub-covered hillside forms one nearly solid near-black light block across y22–56%, reaching the image borders. On its crest at x67%, a small formation of rough pale tan boulders with two vertical split slabs rises from y22% to y10%. The rest of the top quarter is a smooth desaturated slate-blue sky with no clouds. Ground is pale muted gray-taupe sand and compacted gravel, fine gritty texture, no road lines. The black contact shadow extends leftward from the car to the left border around y69–74%.
Chrome is true mirror metal, reflecting the taupe ground as warm bands in the lower body and the dark scrub/sky as irregular black and cool silver horizontal bands in the doors and curved arches. Glass is almost completely black, no bright interior. Hard upper-right sunlight makes the upper and right boulder faces lighter, leaving their left-facing crevices dark. Car midtones are intentionally underexposed and contrasty. Concentrate brilliant small multi-ray starbursts along the rear wing at x17%,y52–56%; roof shoulder x46%,y47–51%; near side shoulder x35%,y56–59%; near wheel lower rim x52%,y70%; and sill x63%,y68%. Thin rays extend vertically several percent of frame height, some subtle red-blue optical fringing. Starbursts must look like real optical cross-screen highlights on chrome, not painted sparkles floating in space. Very subtle film grain, cool slate sky against muted brown ground, razor-sharp car details, largely uniform distant focus, no artificial bokeh. Full bleed portrait crop, no graphic text.
Negative constraints: no front three-quarter view, no car facing left, no modern supercar, no shiny colored paint, no golden chrome, no mountain panorama, no trees, no building, no sunset, no cloudy sky, no racing motion, no driver, no smoke, no excessively large boulder dominating the frame, no additional cars, no illegible typography, no watermark. Preserve low car placement, tall dark background band and empty foreground; do not enlarge the car vertically to fill the portrait.
