READ THE FULL RECONSTRUCTION SPEC
## Reconstruction specification **Target image format:** 768 × 576 px, 4:3 aspect ratio. **Scene type:** A documentary rural architectural photograph showing a deteriorating historic farmstead or village outbuilding, photographed from a shaded dirt/grass yard beneath a large deciduous tree. **Required visual priority:** Preserve the unpolished, dark, slightly underexposed, low-dynamic-range appearance of the supplied photograph. The image should look like an ordinary older digital photograph, not a modern HDR, cinematic, architectural, or real-estate image. --- # 1. Composition and geometry ## 1.1 Camera position and viewpoint - Camera is positioned in an open yard approximately **15–25 m in front of the main building complex**. - Camera height is approximately **1.55–1.75 m above ground**, consistent with a standing person using a compact camera or handheld consumer digital camera. - The camera is aimed approximately **horizontally**, with a very slight downward bias toward the foreground ground plane. - Viewing direction is nearly perpendicular to the principal façade of the central building, but angled slightly toward the right so that: - the front façade of the central house is visible, - the long low connecting structure recedes slightly toward the right, - the right-hand barn presents a broad front/side face rather than a perfectly frontal elevation. - The camera is not centered on the architecture. The image is framed casually, with substantial foreground shadow and ground occupying the lower half. - The scene is viewed from outside the building complex, at ground level rather than from an elevated or drone-like viewpoint. ## 1.2 Perspective and field of view - Estimated equivalent focal length: approximately **32–40 mm on a full-frame camera**, most likely near **35 mm equivalent**. - Horizontal field of view: approximately **52–58 degrees**. - Vertical field of view: approximately **40–44 degrees**, consistent with the 4:3 frame. - Perspective is natural and moderately wide, but not strongly wide-angle. - No obvious fisheye distortion. - Vertical architectural lines remain mostly vertical, with only minor convergence and mild irregularity. - The buildings do not appear dramatically stretched at the edges. - The foreground is enlarged somewhat by the moderate-wide viewpoint, but not exaggerated. - Perspective is ordinary and photographic rather than orthographic or architectural-correction perspective. ## 1.3 Horizon and vertical framing - The effective horizon/eye-level region is approximately **40–45% down from the top edge**, around image row 235–260, though it is partly obscured by buildings and vegetation. - The sky occupies roughly the upper **35–40%** of the image in the gaps above the roofline. - The ground and shadows occupy approximately the lower **45–50%**. - The principal roof ridge is centered slightly above the vertical midpoint. - The composition is weighted toward the center-right by the buildings, while the large tree on the left balances the frame. ## 1.4 Major object placement Percentages below are relative to the full 768 × 576 image. ### Large foreground tree - Main trunk: - occupies approximately **x = 12–23%** - extends from approximately **y = 0–65%** - trunk width varies from approximately **4–7% of image width** - trunk center around **x = 17–18%** - Main trunk enters from the upper edge and descends to the ground at approximately **x = 16–18%, y = 62–68%**. - Branch system spreads across the upper-left and upper-central region: - from approximately **x = 0–56%** - mostly between **y = 0–38%** - Branches are thin, dark, mostly leafless, with sparse brown remaining leaves. - The left edge contains additional dark foliage and shadow, especially from **x = 0–12%**. ### Main central house - Overall visible footprint: - approximately **x = 24–65%** - approximately **y = 25–64%** - Main roof ridge: - begins near **x = 37%, y = 27%** - peaks near **x = 48%, y = 25–26%** - descends toward approximately **x = 62%, y = 37%** - Main red/orange tiled roof: - approximate bounds **x = 27–63%, y = 26–47%** - central upper roof plane forms a broad trapezoid/hipped shape. - Main façade: - approximate bounds **x = 26–59%, y = 36–63%** - old yellow-beige plaster, brick, and exposed masonry. - The façade is irregular and visibly aged rather than planar and clean. - Several windows are placed across the upper front: - left/central windows around **x = 29–39%, y = 39–51%** - another window or dark opening around **x = 45–51%, y = 40–51%** - Main dark doorway/opening: - approximately **x = 34–42%, y = 52–64%** - nearly black interior, irregular rectangular shape. - Chimney: - narrow vertical chimney around **x = 25–27%, y = 26–40%** - dark reddish-brown masonry with a slightly uneven top. ### Low connecting structure - Runs horizontally from the central house toward the right: - approximately **x = 47–78%** - approximately **y = 41–64%** - Has a low red tile roof with a shallow pitch. - Roof edge slopes and recedes slightly toward the right. - The wall below is pale gray-beige plaster with extensive peeling, missing sections, dark stains, and exposed reddish masonry. - This is one of the most visibly deteriorated parts of the complex. - Wall line is approximately at **y = 54–65%**. ### Right-hand barn / large gabled structure - Occupies approximately **x = 69–100%** - Vertical extent approximately **y = 25–68%** - Main triangular gable: - apex around **x = 91–92%, y = 25–27%** - left eave around **x = 76–78%, y = 43–46%** - right eave extends beyond or nearly reaches the right edge around **x = 99–100%, y = 44–47%** - Large wall mass extends down to approximately **y = 68%**. - The gable is made of heavily weathered exposed brick, stone, and crumbling plaster. - Roof plane is reddish-brown and somewhat muted rather than bright orange. - Main lower doorway/opening: - approximately **x = 91–96%, y = 54–67%** - narrow, dark, irregular vertical opening. - The extreme right edge cuts through the building, so the barn is not fully contained within the frame. ### Background trees - Leafless or sparse deciduous trees appear behind the buildings from approximately: - **x = 42–96%** - **y = 18–46%** - Their branches are thin, gray-brown, and low contrast against the sky. - They should not be rendered as dense green woodland. - Additional darker vegetation appears behind the left side of the house and near the far-left edge. ### Foreground ground - Ground begins visually below approximately **y = 55–60%**, although building bases overlap it. - Lower foreground consists of: - dark brown dirt, - patchy green grass, - scattered dry leaves, - irregular shadow patches, - indistinct debris and uneven soil. - A faint dirt or worn pedestrian path runs from the lower-left/center toward the buildings. - There is no clean lawn or maintained garden appearance. ## 1.5 Vanishing structure - Horizontal roof and wall lines converge only mildly toward the right. - The principal vanishing direction is around the **center-right region, approximately x = 68–78%, y = 45–50%**. - Because the buildings are irregular and aged, lines should not be made perfectly rectilinear. - Roof eaves, wall tops, and foundation lines should have slight irregular deviations. - Avoid architectural-rendering geometry with perfectly straight walls, mathematically exact roof symmetry, or corrected verticals. --- # 2. Lighting ## 2.1 Sun direction - Direct sunlight appears to come from the **upper-left/front-left of the camera**, approximately from image-left and slightly above. - Evidence: - the large tree casts a long, dark shadow toward the lower-right/center foreground, - portions of the central façade and roof are illuminated from the left/front, - the foreground contains strong diagonal shadows extending toward approximately **x = 55–75%, y = 80–100%**. - Approximate solar azimuth relative to camera: **left-front, around 30–50 degrees off camera axis**. - Approximate solar elevation: **30–45 degrees above the horizon**. - The shadows are long enough to suggest a relatively low-to-moderate sun, not midday overhead sunlight. ## 2.2 Shadow direction and softness - Tree shadows extend diagonally from upper-left/left-side objects toward the **lower-right**. - Foreground shadows are broad but clearly legible. - The main tree shadow is dark, irregular, and broken by branches. - Shadows under roof overhangs, doorways, and wall recesses are very dark. - Shadow edges are moderately soft rather than razor sharp: - approximately **2–8 px of transition** in open ground areas, - more diffuse where filtered through branches. - Lighting is a mixture of: - hard-to-moderate directional sunlight, - soft sky fill, - dense local occlusion under trees and roof eaves. - Do not use fully soft overcast illumination. The image clearly contains direct sun and distinct shadow structure. ## 2.3 Ambient and sky illumination - Blue sky provides cool ambient fill in exposed surfaces and shadows. - The sky is bright but not blown out. - White clouds are luminous and moderately bright, with gray-blue shaded undersides. - The scene is not evenly illuminated: - sunlit roofs and portions of the façade are moderately bright, - shaded ground and recesses become substantially darker, - the left foreground is especially dark. - Ambient fill is limited, producing strong separation between sunlit and shaded areas. ## 2.4 Relative illumination Approximate relative luminance hierarchy: 1. Bright white cloud tops and sunlit cloud edges. 2. Sunlit red tile roofs and pale sunlit plaster. 3. Blue sky. 4. Green grass in direct light. 5. Weathered brick and brown roof surfaces. 6. Tree trunk, shaded grass, and foreground dirt. 7. Doorways and deep architectural recesses, which approach near-black. - Sunlit architecture is not highly luminous; the photograph remains somewhat dark overall. - Shadows are not completely crushed everywhere, but many deep recesses have very little recoverable detail. - The left foreground is approximately **1.5–2.5 stops darker** than the most directly sunlit façade/roof surfaces. ## 2.5 Overall lighting character - Lighting character: **partly sunny, moderately hard, naturally uneven, slightly low-exposure**. - Not cinematic. - Not HDR. - Not golden-hour orange. - Not flat studio illumination. - Not strongly hazy, though distant background branches and clouds have mild atmospheric softness. - The image has a clear late-season, cool-day outdoor appearance. --- # 3. Color rendering ## 3.1 White balance and color cast - Overall white balance is close to daylight but slightly cool and subdued. - A mild **cyan-blue cast** is present in the sky and cooler shadow areas. - Sunlit walls and roof tiles are warm but should not be exaggerated into orange or golden tones. - Shadows trend toward dark green-blue/brown rather than neutral black. - The image should not have a strong magenta, red, or yellow color cast. - Approximate color temperature: **5,800–6,500 K**, with consumer-camera daylight rendering. ## 3.2 Saturation - Overall saturation: **moderate to moderately low**, approximately 75–85% of a modern vivid-camera rendering. - Sky blue is present but somewhat muted. - Grass is green but dark and not intensely saturated. - Red tile roofs are clearly reddish-orange but subdued by age, shadow, and low exposure. - Brown masonry and tree bark are earthy and desaturated. - Do not intensify all colors globally. ## 3.3 Representative colors These values are approximate and should be treated as target ranges, not flat fills. ### Sky - Open upper sky: - approximately RGB **(73, 111, 145)** to **(91, 130, 163)** - HEX approximately **#496F91 to #5B82A3** - Sky near the horizon and behind branches: - darker, grayer blue around RGB **(65, 94, 117)** - HEX approximately **#415E75** - Sky should have mild tonal variation and slight atmospheric haze, not a perfectly uniform blue gradient. ### Clouds - Sunlit cloud areas: - RGB approximately **(205, 211, 204)** to **(231, 232, 220)** - HEX approximately **#CDD3CC to #E7E8DC** - Cloud shadows: - RGB approximately **(137, 151, 153)** to **(170, 177, 169)** - mildly cool gray with blue-green contamination. - Avoid pure white clipping except in very small cloud highlights. ### Vegetation and grass - Sunlit grass: - dark muted green around RGB **(58, 91, 44)** to **(83, 110, 53)** - HEX approximately **#3A5B2C to #536E35** - Shaded grass: - RGB approximately **(25, 49, 26)** to **(44, 66, 32)** - HEX approximately **#19311A to #2C4220** - Tree foliage and dark vegetation: - deep green-black around RGB **(20, 38, 22)** to **(39, 57, 32)**. - Vegetation should look seasonally sparse, patchy, and somewhat dirty, not lush or manicured. ### Dirt and foreground - Sunlit dirt: - RGB approximately **(82, 66, 48)** to **(113, 88, 56)** - HEX approximately **#524230 to #715838** - Deep shadowed dirt: - RGB approximately **(34, 34, 28)** to **(52, 43, 32)**. - Dry leaves: - muted brown, ochre, and gray tan around RGB **(104, 82, 52)** to **(145, 113, 66)**. ### Roof tiles - Sunlit red/orange tiles: - RGB approximately **(143, 62, 33)** to **(177, 83, 42)** - HEX approximately **#8F3E21 to #B1532A** - Shaded tile areas: - RGB approximately **(84, 45, 30)** to **(112, 51, 31)**. - Tile surfaces should show alternating narrow horizontal rows, but the pattern should be softened by image resolution and age. - Do not make roofs bright saturated terracotta. ### Main plaster and walls - Sunlit yellow-beige plaster: - RGB approximately **(153, 130, 85)** to **(185, 158, 103)** - HEX approximately **#998255 to #B99E67** - Pale damaged plaster on the low structure: - RGB approximately **(156, 149, 119)** to **(190, 179, 139)** - muted gray-beige, with dirt and green/brown staining. - Shaded plaster: - RGB approximately **(80, 73, 55)** to **(112, 92, 61)**. ### Exposed brick and stone - Red-brown brick: - RGB approximately **(111, 62, 42)** to **(147, 79, 48)**. - Gray-brown stone: - RGB approximately **(94, 88, 70)** to **(132, 116, 83)**. - Mortar and eroded plaster should be irregular, dirty, and desaturated. ### Deep shadows - Typical deep shadow: - RGB approximately **(22, 28, 22)** to **(42, 39, 29)**. - Near-black doorways: - RGB approximately **(11, 15, 12)** to **(28, 25, 19)**. - Avoid pure digital black across large areas; retain limited muddy green/brown detail where visible. --- # 4. Tone and exposure ## 4.1 Exposure - Overall exposure is slightly low, approximately **−0.3 to −0.7 EV** relative to a modern balanced exposure. - The image feels darker than a contemporary automatically corrected photograph. - The central building remains readable, but the foreground and recesses are noticeably underexposed. - Do not brighten the full image to reveal all architectural details. ## 4.2 Black point and shadows - Black point is moderately low but not absolutely crushed across the entire image. - Deepest doorways and heavy foliage approach black. - Many shadow regions retain muddy green, brown, or blue information. - Blacks are partially compressed and slightly lifted in some areas due to older digital processing, but doorways remain very dark. - Approximate effective black values: - deepest pixels: RGB **(8–15)** - common shadow floor: RGB **(20–35)**. ## 4.3 White point and highlights - White point is moderately high but not aggressively clipped. - Cloud highlights approach pale gray-white rather than pure white. - Sunlit plaster and cloud tops have restrained highlight detail. - Some very small bright areas may clip, but there is no broad highlight clipping. - Highlight roll-off is limited and somewhat abrupt compared with a modern high-dynamic-range camera. - Do not produce glossy, sparkling, or luminous HDR highlights. ## 4.4 Contrast and gamma - Global contrast: **moderate**, with localized high contrast in tree shadows and doorways. - Midtones are somewhat dark and slightly compressed. - Gamma rendering is approximately ordinary consumer-camera JPEG, with a mildly heavy lower midtone. - The image does not have lifted cinematic blacks or a matte editorial curve. - It also does not have extreme punchy contrast. - Architecture should retain texture through mottled midtones rather than appear cleanly separated into graphic planes. ## 4.5 Dynamic range - Apparent dynamic range is approximately **8–9 stops**, not modern multi-exposure HDR. - Bright sky, cloud, sunlit façades, and dark foreground coexist, but shadow detail is limited. - Exposure should prioritize the overall scene rather than perfectly exposing both sky and shaded ground. - Sky remains moderately detailed while foreground shadow falls dark. --- # 5. Camera and lens characteristics ## 5.1 Lens - Approximate focal length: **35 mm full-frame equivalent**, acceptable range **30–42 mm equivalent**. - Lens is moderately wide but not ultra-wide. - Field of view should preserve natural building proportions. - No strong barrel distortion. - Very slight edge stretching may be present, especially near the right and left borders. - No perspective correction or tilt-shift effect. ## 5.2 Depth of field - Depth of field is relatively deep: - foreground tree, buildings, and background trees are all reasonably recognizable. - Focus appears set at a moderate distance, likely around the building complex. - Foreground ground is somewhat soft due to texture, low resolution, and shadow, not necessarily strong optical defocus. - Background branches are soft because of distance, atmospheric contrast, and image quality. - Do not introduce pronounced portrait-style bokeh. ## 5.3 Perspective distortion - Natural perspective with mild convergence. - Roofs and wall edges do not bend. - Vertical lines may lean subtly due to camera angle, but should remain close to vertical. - The right barn may feel slightly enlarged because it is nearer to the right side of the frame, but not dramatically distorted. ## 5.4 Vignetting - There may be mild darkening toward the corners, especially the upper-left and lower corners, but it is subtle. - Estimated vignetting: approximately **0.2–0.5 stop**. - Do not add an obvious artificial circular vignette. ## 5.5 Chromatic aberration and optical defects - Minor color fringing may occur on high-contrast branches against the blue sky, particularly: - fine branches near the top-left, - roof edges, - bright cloud boundaries. - Keep chromatic aberration subtle, roughly **1–2 px of low-intensity red/cyan or purple/green fringe** at the outer frame. - Avoid conspicuous lens effects. ## 5.6 Camera age and quality - The photograph resembles an older consumer digital camera or compact camera image, approximately mid-2000s to early-2010s in character. - It does not have the clean microdetail, high shadow recovery, or color separation of a modern full-frame camera. - Exposure and color appear mostly automatic and ordinary. - There is no professional architectural correction, controlled polarizer effect, or carefully graded tonal curve. --- # 6. Image texture and processing ## 6.1 Resolution and sharpness - Global sharpness is moderate to low. - The image should retain recognizable edges, but fine details are softened. - Roof tiles, brick, branches, and leaves are visible without being crisply resolved. - Edge sharpness is stronger on nearby high-contrast objects such as: - tree trunk edges, - roof boundaries, - dark doorway edges. - Fine masonry and grass detail should merge slightly at pixel scale. ## 6.2 Microcontrast - Microcontrast is subdued. - Surface texture is visible through coarse tonal variation rather than modern clarity enhancement. - Avoid hyper-detailed brick pores, individual grass blades, or sharply separated roof tiles. - The building should feel textured but slightly muddy. ## 6.3 Noise and grain - Fine luminance noise may be present in: - dark foreground, - shaded vegetation, - building recesses, - blue sky at enlarged viewing scale. - Noise is mild and mostly monochromatic, with possible slight chroma noise in shadows. - It should resemble small-sensor digital noise more than film grain. - Do not add obvious artistic film grain. ## 6.4 Denoising and compression - Some low-level denoising or JPEG smoothing is apparent: - fine branches and foliage lose detail, - dark textures become blotchy, - tiny roof-tile patterns merge. - Use mild JPEG-like compression or resampling softness. - Acceptable compression impression: approximately **quality 75–90 JPEG**, not severely blocky. - Avoid visible large compression blocks or severe ringing. ## 6.5 Sharpening - Moderate consumer-camera sharpening may create slight edge emphasis around: - roof ridges, - branches, - tree trunk, - wall boundaries. - Any halos should be very subtle, approximately **1 px**, with no bright cartoon outlines. - Do not apply modern clarity, texture, or AI edge enhancement. ## 6.6 Resampling and softness - The image should look slightly softened by: - modest lens resolution, - small sensor, - compression, - resizing, - low-light/shadow noise reduction. - Fine detail should not be reconstructed as unnaturally crisp. - Avoid painterly texture, excessive photographic grain, or plastic AI smoothness. --- # 7. Photographic character The defining character is an **ordinary, slightly dark, casually framed rural snapshot** of an old, decaying building complex under partly sunny daylight. Important photographic traits: - The frame is not geometrically perfect or carefully balanced. - A large tree partially obstructs and dominates the left side. - The foreground is mostly shadow and rough ground rather than a visually attractive leading path. - The buildings are historically interesting but photographed without deliberate real-estate or documentary staging. - The architecture is visibly deteriorated: - peeling plaster, - exposed brick and stone, - uneven walls, - dark openings, - aged roof tiles, - mismatched repairs. - The image has moderate underexposure, especially in the foreground and recesses. - The sky is attractive but not spectacularly graded; it is an ordinary muted blue with scattered white clouds. - The colors are earthy and restrained. - The grass is patchy and dark, not lush. - Branches are sparse and somewhat messy. - The composition includes dead space, deep shadows, and partially obscured elements. - The right barn is cropped by the right frame edge. - Fine details are softened rather than resolved with professional sharpness. - The building surfaces have muddy, irregular tonal transitions that should remain intact. - The image should feel like a real photograph captured quickly in available light, not like a reconstructed ideal view of a picturesque ruin. Specific imperfections that must remain: 1. Slightly low overall exposure. 2. Dark, underexposed foreground. 3. Deep, nearly black doorways and recesses. 4. Uneven illumination across the building façade. 5. Mildly muted colors. 6. Slight blue/cyan coolness in sky and shadows. 7. Soft or smeared fine detail in branches, roof tiles, grass, and masonry. 8. Irregular old walls and roof edges. 9. Composition partly obstructed by the tree. 10. Cropping of the large right-hand structure. 11. Lack of perfect architectural symmetry. 12. Patchy, unmaintained ground. 13. Mild consumer-camera noise and compression softness. 14. Limited shadow recovery. 15. No polished HDR separation between sky, buildings, and foreground. --- # 8.

It must look like the supplied photograph itself—not like a cleaner, brighter, sharper, more colorful, more cinematic, or more historically restored version of the same scene.
