yes the problem is that the current prompt treats integration as colour grading when the real issue is geometric optical lighting edge scale perspective and pixel level continuity a background can have perfect colour matching and still look obviously pasted in i d rewrite the entire section to tell the model to reconstruct the background as if it were actually photographed from the villa rather than blend a separate image into it if you upload the current image i can also tailor the prompt to the exact photoshop looking failure points here is the stronger full version critical reconstruct the background as one real photograph the inserted valley hills houses vegetation sea and sky currently look like separate imagery composited behind the original villa this is not acceptable the goal is not simply to colour match soften or blend the inserted background the background must be reconstructed and transformed so convincingly that it appears to have physically existed behind the villa at the exact moment the original photograph was captured the final image must look like one untouched photograph not a photograph with a digitally inserted landscape the original foreground photograph is the absolute photographic reference do not alter the photographic character of the original villa architecture balcony furniture vegetation or foreground unless necessary to create a physically believable transition 1 first priority make the background belong to the original camera treat the original photograph as if it came from a real camera positioned at the existing camera position the inserted landscape must be reconstructed from that same camera position camera height camera orientation viewing direction lens perspective focal length field of view perspective geometry image projection sensor characteristics depth of field optical rendering exposure lighting conditions do not simply place a landscape photograph behind the villa the inserted environment must be reprojected and perspective matched to the original photograph the valley hills houses vegetation sea and horizon must occupy positions that are physically plausible from the original camera viewpoint 2 perspective and scale must match this is one of the most important requirements the background must have the same perspective geometry as the original photograph do not allow incorrect horizon height incorrect camera elevation incorrect landscape scale oversized distant hills miniature looking houses incorrect valley proportions incorrect sea position distorted slopes incompatible vanishing behaviour mismatched field of view mismatched lens compression background geometry that looks like a flat photograph the apparent scale of every distant object must make sense relative to the villa and camera houses vegetation hills and landscape features must have believable physical scale and distance the landscape should feel like a real three dimensional environment located behind the villa not a 2d image placed behind a mask 3 preserve the original foreground exactly the original villa and foreground photograph are the primary photographic reference preserve the original architecture balcony walls doors windows railings furniture foreground vegetation visible surfaces shadows reflections existing textures existing photographic detail original perspective original lens characteristics do not re render the foreground unnecessarily do not make the foreground look ai generated do not sharpen smooth repaint or reinterpret the architecture simply to make compositing easier the new background must adapt itself to the existing photograph do not force the original foreground to conform to the inserted background 4 build a physical depth structure the transition behind the villa must contain believable physical depth do not treat the entire background as one flat layer construct the scene conceptually as villa balcony edge immediate vegetation nearby terrain valley middle distance hills distant hills sea horizon sky each region must have a believable physical relationship with the next the landscape must recede naturally into the distance avoid obvious artificial layer boundaries there should be no visual impression of foreground photograph landscape layer sky layer instead it should read as one continuous physical environment photographed from one camera 5 edge and occlusion integration do not rely on a simple soft mask around the background the boundary between the original foreground and the reconstructed landscape must follow the actual physical structure of the scene respect balcony edges railings architectural openings vegetation branches leaves thin structures distant objects visible through openings natural occlusion foreground depth background elements must correctly disappear behind foreground objects foreground objects must remain in front of the landscape do not allow background pixels to bleed over architectural edges do not create halos glowing edges soft cutout borders bright outlines dark outlines colour fringes smeared vegetation edges artificial feathering obvious masking transitions fine foreground structures must remain naturally separated from the background 6 optical integration same lens not just same colour the background must inherit the optical characteristics of the original photograph match lens perspective lens distortion corner behaviour sharpness falloff microcontrast depth rendering natural softness resolution grain structure chromatic behaviour highlight rendering tonal response do not make the inserted background unnaturally sharper than the original photograph do not make it artificially blurred either the background must have the same apparent optical resolution and photographic rendering as objects photographed at equivalent distances with the original camera avoid the common compositing appearance where foreground real camera photograph but background ultra clean digital image the entire image must share one optical character 7 match lighting not just colour the background must be illuminated by the same real world lighting condition as the villa analyze the original photograph and reproduce its apparent sun direction light direction light softness time of day shadow behaviour highlight intensity sky illumination ambient illumination reflected light overall illumination level the landscape must not appear to come from a different time of day do not combine warm villa cool landscape bright foreground dark landscape cloudy foreground sunny landscape soft light foreground hard light landscape the background should appear to have been illuminated under the same lighting event 8 match exposure and tonal response the background must share the same exposure as the original photograph match overall brightness black point shadow density midtone brightness highlight brightness highlight rolloff contrast curve dynamic range local contrast tonal compression do not independently colour grade the valley sea and sky the entire background should respond to light in the same way as the original photograph avoid hdr appearance excessive local contrast crushed blacks clipped highlights overly bright distant landscape artificially flat shadows excessive clarity excessive sharpness 9 colour integration match the original photograph s actual colour response match white balance colour temperature tint saturation hue relationships shadow colour midtone colour highlight colour vegetation colour earth tones architectural colour influence sky colour sea colour do not make the background generically cinematic do not add a new colour grade do not push the background toward blue green teal orange cyan or any other stylistic colour unless that colour is already present in the original photograph the original image determines the colour palette the background must inherit that palette 10 natural depth without excessive haze create realistic depth through scale perspective detail reduction contrast reduction and optical distance not through an obvious haze overlay nearby landscape clearer more detailed slightly higher local contrast middle distance landscape subtly softer slightly reduced local contrast slightly reduced microdetail distant landscape naturally softer slightly lower contrast slightly compressed tonal range these changes must be extremely gradual do not introduce fog mist milky veiling grey overlay white veil excessive blue haze artificial atmospheric fog uniform haze obvious distance fog atmospheric perspective must be subtle enough that the viewer does not consciously notice a haze effect the purpose is to create believable depth not visible haze 11 do not use haze as a compositing tool this is critical do not attempt to hide mismatched background imagery by adding haze haze must never be used to conceal incorrect edges incorrect perspective incorrect scale incorrect colour incorrect lighting incorrect exposure incorrect sharpness incorrect resolution incorrect horizon placement fix those problems directly never solve a compositing mismatch by making the background hazier the landscape must remain visually clear 12 natural colour and detail fall off distance should affect the landscape naturally as distance increases allow only subtle changes in contrast microdetail saturation tonal separation apparent sharpness do not create obvious horizontal bands do not divide the background into artificial foreground midground background grades the viewer should not be able to identify where one atmospheric or colour zone begins and another ends the entire landscape must behave as one continuous environment 13 sky horizon and sea must belong to the same world the sky must not look like a separately pasted sky photograph the horizon must have the correct height curvature if applicable perspective brightness contrast atmospheric transition the sea must occupy the correct physical position relative to the horizon and surrounding terrain the sea must match the same exposure white balance colour response contrast texture scale optical softness lighting condition do not make the sea unnaturally saturated do not make it artificially turquoise do not make it overly blue do not make it hdr like do not make the sea sharper or cleaner than the rest of the photograph the sea must look as though it was photographed through the same lens on the same camera 14 vegetation and houses must have photographic consistency inserted vegetation and houses must not look like individually generated objects they must belong naturally to the landscape match their scale perspective lighting sharpness texture resolution colour shadow behaviour distance orientation avoid the appearance of isolated ai generated objects pasted into the scene the landscape should contain natural visual continuity between objects houses should sit physically within the terrain vegetation should grow from the terrain rather than appear placed on top of it 15 match image resolution and detail character the inserted background must have the same perceived photographic resolution as the original do not introduce hyper detailed ai textures excessive foliage detail artificial sharpening crispy edges excessive microcontrast plastic textures painterly textures overly smooth ai surfaces the background should contain the same level of believable photographic information as the original image if the original photograph has natural softness preserve it if the original photograph has fine photographic grain reproduce the same grain character consistently 16 match motion lens and micro softness the background must not look digitally perfect compared with the original match any natural lens softness slight image softness sensor rendering photographic grain subtle compression optical falloff natural detail loss do not apply a generic blur to the entire background the softness must correspond to distance and optical rendering not to an obvious post processing filter 17 no visible compositing signature the final image must contain absolutely no obvious evidence that separate imagery was inserted eliminate hard masks soft masks halos cutout edges colour seams brightness seams contrast seams sharpness seams resolution seams perspective mismatches horizon seams atmospheric bands pasted looking objects inconsistent grain inconsistent lighting inconsistent shadows inconsistent white balance there must be no rectangular region that looks separately processed there must be no boundary where the generated background begins 18 do not overprocess the image this is critical do not use heavy haze blur sharpening clarity dehaze saturation contrast colour grading hdr atmospheric effects cinematic effects glow bloom the goal is photographic realism not a stylized image the final result should look like a normal high quality photograph captured in camera 19 the original photo always wins whenever there is uncertainty the original photograph takes priority do not modify the original photographic character merely to make the inserted landscape easier to integrate the inserted environment must adapt to the original match the original camera perspective geometry lighting exposure colour optical rendering detail grain in that order do not invent a different photographic style 20 final realism test before considering the image complete evaluate it as though it were a genuine photograph ask does the background appear to physically exist at the exact location behind the villa does the landscape have the correct perspective from the camera position do the distant objects have believable scale does the lighting come from the same environment does the background have the same optical character as the foreground do the edges and occlusions behave like real physical objects does the sea belong to the same photograph does the sky belong to the same photograph does the landscape have natural depth without obvious artificial haze is there any region that looks like a separate photograph if any answer suggests compositing reconstruct and correct the background rather than hiding the problem with haze blur or colour grading absolute final requirement the final image must not look like original villa photo inserted landscape it must look like one real photograph of the villa with the landscape physically present behind it the integration must come primarily from correct perspective correct scale correct depth correct occlusion correct lighting correct exposure correct colour correct optical rendering correct detail correct grain not from haze minimal haze no fog no milky veil no artificial atmospheric overlay the landscape should remain clear and naturally photographic the final viewer should have no reason to suspect that the background was inserted at all one camera one lens one exposure one lighting condition one optical response one colour response one physical environment one photograph the biggest conceptual change is fix the mismatch at its source rather than asking the model to hide the mismatch with atmospheric effects that should address the obvious photoshop composite appearance much more effectively
