{
"subject": "a four-door sports car, fictional and with no brand at all, in metallic graphite grey with a satin finish, parked alone on the shoulder of a mountain road; the front points to the left of the frame and the body sits at three quarters, showing the whole side all the way to the rear; large black honeycomb front grille, no badge; slim LED headlights with a lit white light strip; bumper with two dark air intakes underneath; smooth, empty plate holder, no number and no letter; dark alloy wheels with double spokes and low-profile tyres, the front wheel slightly turned so the rim shows; dark glass, black window trim and mirrors in the body colour",
"scene": "dark, rough asphalt road, the worn and flaking white centre line running from the bottom right corner into the frame; loose stones and low scrub on the shoulder to the left; corrugated metal guardrail behind the car, on both sides; low bushes with yellowed leaves at the edges; past the guardrail the valley opens into layers of blue-hazed ridges, lighter and lighter to the horizon, with a sea of low clouds caught between the mountains on the left side",
"composition": "vertical image in 3:4 ratio; the car takes the middle band, a little to the right of centre, with its front turned to the left; the bottom third is only asphalt, with the white line cutting across it diagonally; the top half is mountains and sky, with the horizon about a third of the way down from the top",
"camera": "headlight height, camera low and about five metres from the car, aimed at its front at three quarters; medium-distance lens, no distortion at the edges; the whole car sharp, with a slight loss of definition in the corners and on the farthest ridge",
"lighting": "low sun on the horizon, to the left of the frame, almost touching the mountain line, with a golden glare spread around it; warm backlight lighting up the roofline, the bonnet and the wing on the sun side; a stretched reflection of the orange sky on the windscreen and the bodywork; a long shadow of the car falling to the right across the asphalt; high contrast, with closed shadows under the car and in the wheels",
"color_palette": "orange and gold in the low sky, in the sun and on the lit asphalt, greyish blue in the layers of ridges and high in the sky, graphite grey on the car, closed black in the wheels, the grille and the shadows, dry yellow in the bushes and dirty white in the road line",
"materials": "satin metallic paint with a soft reflection, dark windscreen glass, matte rubber on the tyres, brushed metal on the guardrail, grainy asphalt with visible gravel, thin haze between the mountains",
"style": "editorial automotive photography, realistic and cinematic, with nobody in the scene; fine film grain, dense blacks, high contrast and colour split between the warm sun and the cold ridges, the mood of late afternoon on an empty road",
"details": "preserve the car alone on the shoulder with its front to the left, the honeycomb grille with no badge, the smooth empty plate, the turned front wheel, the guardrail behind, the worn white line in the bottom right corner, the sun touching the mountain line on the left, the layers of blue ridges and the sea of clouds in the valley",
"negative_prompt": "people, hands, faces, text, letters, numbers, plate with a number, badge, real car brand, logo, watermark, signature, other cars, traffic, city, drawing, illustration, AI artifacts"

How to use
A good car photo is place and time: the right overlook and the ten minutes before the sun drops behind the ridge. This prompt builds the whole scene, in 3:4, with the car parked on the shoulder and the valley open behind it. It works in ChatGPT, Gemini and NanoBanana.
1. Paste the prompt without sending any photo. The car comes out fictional, with no badge and no plate, and the road comes with it.
2. Swap the car in the subject field: colour, type (hatchback, pickup, SUV) and the design of the wheels. The rest of the JSON holds the scene.
3. The time of day lives in the lighting field. Swap the low sun for an overcast sky, rain, or night with the headlights on.
4. For a story or a reels cover, ask for the same scene in 9:16 and say "leave the top third empty": that is where the text goes.
5. Change one field at a time. Swapping car, light and setting together gives you another image, not yours adjusted.
Tip: ask for the same scene from the rear, with the sun facing the camera. The two together make a pair for an ad or for the feed.
