Use case: photorealistic-natural. Create ONE finished standalone photographic website background for the Fire & Ember collection. Real observational outdoor fire photography at night, quietly beautiful and cozy. The photograph should feel captured rather than arranged. Physically plausible irregular combustion: transparent thin flame edges, pale straw-yellow hottest tongues over deeper orange bases, occasional faint blue only right at a burning wood edge, ember light confined to cracks, matte black char and friable gray-white ash. Flame motion has slight natural softness while wood and ground retain genuine detail. Mild real sensor grain in shadows, gentle lens contrast and photographic highlight rolloff; do not recover every shadow. Blacks are deep but not a cutout background: faint contiguous ground or air gives spatial grounding near the subject. Only the fire illuminates the immediate surroundings, with irregular occlusion shadows and rapid natural falloff. No fill lights, no perfectly circular pool of light, no HDR, no artificial glow cloud, no sharpened orange outlines, no smooth CGI surfaces, no plastic wood, no symmetrical teepee logs, no uniformly arranged stone ring, no bonfire spectacle, no excessive particles. Restrained charcoal, soot, muted copper, ochre and pale golden flame. Protect the specified large quiet negative space for later website typography. Full bleed. No people, hands, buildings, camping gear, stars, moon, text, lettering, logo, UI, watermark, borders or collage. Required framing: 3:4. Scene: PORTRAIT vertical 3:4 night photograph. Small low campfire centered horizontally near the bottom at 78 percent image height; irregular collapsed wood and flame together about 18 percent of image width. Top 65 percent near-black air, perfect quiet space for a mobile headline. A blackened log lies flat and a shorter broken piece rests diagonally on it, flame curls sideways through the gap, glowing coals sit beneath. Modest light reveals contiguous grainy earth just around the fire, with scattered nonrepeating ash and blackened bark pieces. Subject grounded, not an isolated cutout. A thin barely visible smoke wisp dissipates before reaching the central frame. Quiet low flame not tall bonfire. 50mm f/4 natural night exposure.
