Use case: photorealistic-natural. Create one 21:9 cinematic restaurant website background with no text or UI. Photograph a real, freshly served lunch at a coastal Italian restaurant, from seated eye level angled down slightly, with a 50mm lens at f/4. On the right half of the frame, a simple white porcelain plate holds an appetizing grilled sea bass fillet with delicate golden crisp skin, visible irregular flakes, a little olive oil, a charred lemon half and a few fresh herbs. One small side dish of blistered tomatoes and an ordinary thin drinking glass of water sit farther back. Ivory cotton tablecloth with a fine uneven weave, relaxed natural folds and a small soft shadow beneath the plate. Left third is calm softly shaded tablecloth and softly out-of-focus dark olive restaurant interior, usable for headline placement without an artificial gradient. Late afternoon sunlight from a nearby window falls across the food and produces beautiful natural shadow shapes; restrained cool ambient fill, true whites and greens, not an orange filter. A compelling restaurant campaign photograph: food is the focus, warm welcoming atmosphere, authentic small cooking irregularities, delicate moisture and local reflections, imperfectly folded cloth. Natural photographic detail and highlight rolloff, selective focus without excessive blur. It must look like a photograph made in a working restaurant, not a 3D render or a symmetrical stock-food flatlay. No rustic brown wood, distressed texture, food shaped into perfect repeating patterns, plastic glaze, theatrical steam, people, lettering, logos or watermark.

Final focus refinement: Edit the provided restaurant photograph. Change ONLY the depth of field: reduce the background blur substantially, as though captured at f/11 rather than f/4. Make the restaurant chairs, tables, window frames, plants and coastal view clearly recognizable with natural photographic detail. Retain a small, believable amount of distance softness; no artificial sharpening halos or HDR. Preserve the exact 21:9 framing, camera angle, foreground sea bass plate, grilled lemon, herbs, glass, tomatoes, ivory woven tablecloth, open left-side headline space, warm directional sunlight, shadows and natural color. Keep the food crisp and appetizing. Do not redesign or restyle the scene, move objects, add text or introduce people. The only requested visual change is a deeper, more natural plane of focus through the restaurant background.
