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: 16:9. Scene: Horizontal 16:9 close documentary study of ONE delicate flickering tongue of fire escaping an irregular crack in a real charred hardwood log on the RIGHT third. Log extends diagonally out through the lower right edge, not floating. Thin partially transparent flame is forked, bent and momentarily interrupted by combustion turbulence, pale yellow interior and faint orange edge, never a smooth teardrop or ribbon sculpture. Char has lengthwise grain, friable ash and tiny glowing points only at the burning edge. Flame is about 15 percent of image height, wood less than a quarter of the frame. Left two thirds deep black negative space. Captured 85mm f/4 1/160 second, small real motion blur in flame, no uniform super-sharp edges.
