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 intimate end-of-evening photograph of a dying campfire. A small flat uneven charred log lies across lower 20 percent of frame, enters from right, and disappears into the darkness toward left. One very low weak amber flame only 5 percent of frame height at lower right licks its underside. A few faint deep-red coals underneath and uneven pale ash at the contact points. No active roaring fire. Top two thirds of the photograph are calm almost-black air, just one faint transparent smoke thread immediately above the tiny flame. Soft honest low-light detail, gentle flame movement, 85mm f/4, grounded scale and muted colors.
