GPT Image 1.5 Prompt Examples
Clear prompts significantly improve output quality. Below are structured examples.
Example 1: Cinematic Scene
Prompt: A lone astronaut stands at the edge of a collapsed highway overpass on a terraformed Mars, dusk light casting long amber shadows across red desert dunes that have swallowed the road. The visor reflects a distant colony dome glowing faintly on the horizon. Shot on anamorphic lens with subtle lens flare, shallow depth of field. Muted teal and burnt orange color grade reminiscent of Denis Villeneuve's visual style. Fine dust particles suspended in the air catch the last rays of light.
Example 2: Product Advertisement
Prompt: A matte black premium wireless earbud case sits slightly open on a slab of raw dark marble, one earbud hovering just above the case as if magnetically suspended. A single droplet of water rests on the earbud surface to emphasize water resistance. Soft directional studio lighting from the upper left with a clean gradient background shifting from charcoal to warm cream. The lighting produces a sharp specular highlight along the earbud's edge. Minimalist luxury product photography, razor-sharp focus.
Example 3: Text Rendering Scene
Prompt: A weathered wooden sign nailed to a crooked fence post in a misty countryside field. The sign reads "NOWHERE — 0 miles" in hand-painted white serif lettering with visible brushstroke texture and slight paint drips. Morning fog rolls across tall wet grass behind the sign. The wood grain is richly detailed with cracked paint and rusty nail heads. Photorealistic, natural overcast lighting, shallow depth of field with the background softly blurred.
