READ THE FULL RECONSTRUCTION SPEC
## Reconstruction specification **Frame:** Landscape photograph, approximately **3:2 aspect ratio** (768 × 512 px). Reproduce the ordinary, unembellished appearance of a rural field photograph, not a polished landscape image. ### 1. Composition and geometry - **Camera position:** Low-to-moderate standing height, approximately **1.2–1.6 m above the ground**. The camera looks across the field, not straight down at it. - **Viewing direction:** Nearly level, with a modest downward pitch of roughly **5–10°**. The foreground furrows and clods remain prominent, while the horizon sits low in the frame. - **Horizon:** An uneven, distant land line runs across approximately **y = 27–30%** of the image height. It is mostly horizontal, with subtle low rises and dips; do not make it mountainous or sharply defined. - **Sky:** Occupies about the upper **27–29%** of the frame. It is pale and lightly hazed, with faint, diffuse horizontal cloud or haze traces rather than distinct cloud forms. - **Field:** Ploughed earth fills most of the frame, from the horizon down to the bottom edge. The main dark-brown field occupies the left and central areas and extends into the middle-right. - **Ploughed surface:** Irregular, coarse clods and furrows dominate the foreground. The furrows read as broadly horizontal bands across the frame, with slight diagonal variation and perspective compression toward the horizon. Texture is largest and most legible near the bottom; it becomes smaller and less distinct in the distance. - **Grassy verge:** A strip of green grass borders the field on the right. Its boundary begins around **x = 90–94%** near the upper field and slopes diagonally leftward toward about **x = 54–58%** at the bottom edge. It is broadest in the lower-right corner and irregular rather than geometrically straight. - **Distant land:** A narrow strip of low green-brown fields lies just below the sky, spanning nearly the full width. It is faint and softened by distance. - **Perspective:** Natural, moderately wide perspective. Furrow lines compress toward the far field; there is no strong, obvious single vanishing point. Any apparent convergence is distant, near the horizon around the central-to-right part of the image. - **Lens estimate:** Approximately **30–40 mm full-frame equivalent**, with a moderate field of view. Avoid exaggerated wide-angle perspective. - **Absent elements:** No visible buildings, road, fences, people, vehicles, trees, or prominent structures. ### 2. Lighting - **Sun:** Direct sunlight appears to come from the **upper-left / front-left** of the camera, at a relatively low elevation, approximately **15–25°**. The precise sun position is not directly visible, so keep the direction impression subtle rather than adding a visible sun or conspicuous flare. - **Shadows:** Furrows and clods have strong dark sides and undersides. Shadows generally fall across the furrow structure toward the **lower-right / right**, with some variation from the irregular ground. The grass at the bottom-right is notably shaded. - **Shadow quality:** Distinct and moderately hard-edged, consistent with direct low-angle sun, but broken up by the lumpy soil and grass. Do not turn them into perfectly sharp graphic shapes. - **Ambient light:** Some diffuse sky fill remains in the shadows, but deep furrows and lower-right grass are still very dark. - **Relative brightness:** Sunlit soil clods and grass are much brighter than the furrow hollows. The lit earth is warm ochre-brown; shadowed earth approaches very dark brown or near-black. The sky is bright but pale. - **Overall character:** Natural, high-contrast directional daylight with a slight hazy distance. It is not studio-soft, flat, or cinematic. ### 3. Color rendering Approximate colors below are visual targets, not exact sampled pixel values. - **White balance / cast:** Daylight-balanced overall. The soil and sunlit grass have a mild warm-yellow cast, while the sky is pale blue-cyan. Avoid a strong global warm or cool filter. - **Sky:** Very light blue to blue-white, approximately **#E6F3F6 to #F1F6F4**. It is low-saturation and slightly hazy; the horizon area tends toward pale cream-gray. - **Distant horizon fields:** Muted, low-saturation olive and yellow-green, approximately **#858B55 to #A5A06A**, softened by atmospheric haze. - **Sunlit soil:** Uneven warm earth browns and ochres, approximately **#76532D to #9A713B** on exposed clods. - **Shadowed soil:** Dark brown to nearly black, approximately **#241D15 to #3C2A1A**. Retain some clod detail where visible; not every shadow is featureless black. - **Grass verge:** Mixed natural greens, olive, and yellow-green. Sunlit blades are approximately **#557438 to #718744**; deeper shaded areas are approximately **#202A1C to #35432A**. The lower-right is especially dark. - **Highlights:** Pale sky and sunlit soil are bright but not glossy. The soil highlights remain earthy, not orange or golden. - **Saturation:** Moderate-to-low overall. Greens are present but not vivid; sky is notably unsaturated. Do not boost color intensity. ### 4. Tone and exposure - **Exposure:** A normal daylight exposure with a bright sky and substantially darker ground shadows. The sky is close to white in places but still retains a faint cool tint and tonal variation. - **Contrast:** Medium-high locally, chiefly because of sunlight on clods against dark furrow hollows. Do not raise global contrast beyond this natural directional contrast. - **Black point:** Deep shadows approach black, particularly in furrow gaps and at the lower-right edge, but the overall image is not uniformly crushed. - **White point:** Bright sky reaches near-white; soil highlights are appreciably darker. Avoid adding brilliant clipped white highlights to the earth. - **Dynamic range:** Limited to moderate in the photographic rendering: bright sky and dark ground coexist without a strongly processed HDR appearance. - **Midtones:** Earth and grass midtones are somewhat subdued and earthy, not lifted into a bright, clean, airy look. - **Highlight roll-off:** Fairly gentle in the sky, with the brightest areas becoming pale rather than sharply clipped. Some slight washout or loss of detail in the brightest sky is acceptable. - **Shadow depth:** Preserve the conspicuously dark furrows and lower-right vegetation. Do not lift the shadows until the soil appears evenly exposed. - **Gamma:** Ordinary photographic midtone rendering; neither especially flat nor aggressively contrast-shaped. ### 5. Camera and lens characteristics - **Depth of field:** Broad. The foreground soil is clearly textured, and the field remains generally in focus into the middle distance. The far horizon is softer mainly from distance and haze, not from strong lens blur. - **Distortion:** Little obvious barrel or pincushion distortion. Keep the horizon and field geometry natural. - **Perspective distortion:** Moderate and plausible for a standard-to-moderately-wide lens. Foreground clods are larger than distant ones, but not dramatically enlarged. - **Vignetting:** No strong visible vignette. The dark lower-right is attributable primarily to shade and vegetation, not a circular lens falloff. - **Chromatic aberration:** No prominent colored fringing should be introduced. - **Camera character:** A straightforward outdoor photograph, plausibly from a consumer digital camera. Do not imitate a high-end, ultra-clean, large-format landscape image. ### 6. Image texture and processing - **Sharpness:** Moderate. The individual soil clods are visible, but the image does not have extreme crispness or high microcontrast. - **Detail:** Coarse ground texture is the dominant fine detail. Grass blades are discernible in places but merge into darker clumps in the shade. - **Noise and grain:** Little obvious noise or film grain. Do not add a pronounced grain effect. - **Compression / resolution:** Preserve the modest, ordinary-resolution photographic appearance. Fine distant details are soft and slightly indistinct; do not invent extra texture or clarity. - **Processing:** No obvious HDR, dramatic local contrast, selective color, or heavy sharpening. Avoid sharpening halos around clods or along the horizon. - **Softness:** The distance and sky are mildly soft or hazy, while nearby soil texture remains recognizable. Keep that difference rather than applying uniform crispness. ### 7. Photographic character to preserve This image is defined by its **uneven, clod-filled dark ploughed earth**, the **diagonal strip of grass at the right**, and the contrast between **low, pale hazy sky** and **deep furrow shadows**. It feels like a simple documentary field photograph taken in direct low-angle daylight. The earth is rough and irregular; the lighting is uneven; the sky is pale rather than dramatic; and some foreground shadows are very dark. Preserve the slightly subdued color and the softened distant horizon. Do not replace these ordinary photographic qualities with a more picturesque or carefully art-directed version. ### 8. Anti-beautification instructions - Do **not** saturate or deepen the blue of the sky. - Do **not** add dramatic clouds, sunbeams, flare, or a vivid sunset color cast. - Do **not** brighten the dark furrows or lower-right shadows to reveal uniform detail. - Do **not** make the soil smoother, more evenly patterned, or more geometrically neat. - Do **not** make the grass brighter, more saturated, or lushly emerald. - Do **not** warm the entire scene or make the soil orange-gold. - Do **not** add clarity, microcontrast, aggressive sharpening, HDR, or cinematic grading. - Do **not** increase global contrast beyond the existing sunlit-clod / dark-furrow contrast. - Do **not** make the horizon sharper, the distant fields more detailed, or the scene more pristine. - Do **not** remove the pale haze, subdued color, coarse ground irregularity, or deep shadow areas.
