Main ChatGPT prompt morning:

Enhance this photograph to high-end photorealistic quality.

Improve overall light realism with crisp EARLY-MORNING natural light producing subtle reflections.

Same camera angle, do NOT crop the image.

Keep the building geometry, volumes, proportions, and architectural details exactly unchanged.

Refine the concrete facade to appear smooth, glossy, and realistically reflective.

Enhance windows with accurate reflections of sky, surroundings, and morning light, while subtly revealing realistic interior spatial details behind the glass.

Increase realism of vegetation: trees, plants, grass, shrubs, and bushes should show fine natural detail, varied shades of green, realistic contrast, soft shadows, and balanced color palette.

Improve tree leaves locally with glossy surfaces, fine textures, and multiple tonal variations.

Refine asphalt streets and sidewalks with realistic wet patches and water reflections.

Adjust sky to remain clear but more natural and lifelike.

Apply professional photographic color correction with reduced saturation, deeper shadows, brighter highlights, and natural dynamic range.

Do not alter composition or geometry—only enhance photorealistic materials, lighting, textures, and surface details. 

Main ChatGPT prompt evening:

Enhance this photograph to high-end photorealistic quality with a WARM EVENING atmosphere. Introduce romantic evening OVEREXPOSED lighting with warm tones, soft highlights, and pronounced chiaroscuro contrast between light and shadow. Increase the brightness on top of the image.

Same camera angle, do NOT crop the image.

Keep the building geometry, volumes, proportions, and architectural details exactly unchanged. Refine the concrete facade to appear smooth, slightly glossy, and subtly reflective under warm evening light. Enhance windows with realistic reflections of the evening sky, surrounding environment, and warm light sources, while gently revealing interior spatial details illuminated from inside. Improve realism of vegetation: trees, plants, grass, shrubs, and bushes should display natural evening color shifts, fine details, deeper shadows, and soft contrast. Locally enhance tree leaves with fine textures, gentle gloss, and varied warm-to-neutral green shades. Refine asphalt streets and sidewalks with realistic wet areas reflecting warm lights and sky glow. Adjust the sky to a clear, realistic evening gradient with natural depth. Apply professional photographic color grading with warm highlights, deeper shadows, reduced saturation, cinematic chiaroscuro balance, and romantic tonal depth. Do not alter composition or geometry—only enhance photorealistic lighting, materials, textures, reflections, and atmosphere. Sky can be quite bright. 

Main ChatGPT prompt winter

Enhance this photograph to high-end photorealistic quality with a cold winter atmosphere. Introduce bright, crisp winter daylight with cool color temperature and high clarity.

Same camera angle, do NOT crop the image.

Keep the building geometry, volumes, proportions, and architectural details exactly unchanged. Refine the concrete facade to appear smooth, slightly glossy, and realistically reflective under cold winter light. Enhance windows with accurate reflections of the pale winter sky, surroundings, and bright diffuse light, while subtly revealing WARM LIT interior spatial details. Cover all vegetation with natural-looking snow: trees, plants, grass, shrubs, and bushes should appear realistically snow-laden, with fine details, soft cold shadows, and desaturated winter color palette. Locally enhance tree branches and leaves with snow accumulation, icy highlights, and subtle tonal variations. Refine asphalt streets and sidewalks with patches of snow, ice, and cold reflective wet surfaces. Adjust the sky to a bright, overcast winter appearance, almost white, with realistic atmospheric depth. Apply professional photographic color correction with cooler highlights, reduced saturation, bright midtones, crisp contrast, and clean winter dynamic range. Do not alter composition or geometry—only enhance photorealistic winter lighting, materials, textures, reflections, and atmosphere.

Main ChatGPT prompt rain

Enhance this photograph to high-end photorealistic quality with a rainy day atmosphere. Introduce overcast grey daylight with dense clouds, diffused low-contrast lighting, and heavy fog softening depth and distance. Keep the building geometry, volumes, proportions, and architectural details exactly unchanged. Refine the concrete facade to appear smooth, darkened, and glossy due to wetness, with realistic rain-soaked reflections. All exterior surfaces should be wet: facade, windows, streets, sidewalks, and surrounding elements. Add visible falling rain with natural motion blur and scale variation. Enhance windows with strong wet reflections of the grey sky and environment, while the only warm light in the scene comes from interior spaces, softly glowing through the glass and contrasting with the cold exterior. Vegetation should appear rain-soaked and heavy: trees, plants, grass, shrubs, and bushes with darker tones, increased saturation from moisture, fine wet details, and soft shadows. Locally enhance leaves with water droplets, glossy surfaces, and subtle tonal variation. Refine asphalt streets and sidewalks with puddles, standing water, and strong reflections of windows and sky. Adjust the sky to uniform grey with layered rain clouds and atmospheric haze. Apply professional photographic color grading with cool tones, muted saturation, low contrast softened by fog, deep wet shadows, and cinematic rainy-day realism. Do not alter composition or geometry—only enhance photorealistic lighting, weather effects, materials, textures, reflections, and atmosphere.
