background colour tonal atmospheric integration match the inserted valley hills houses sea and sky to the original photograph so they appear to have been captured by the same camera lens and exposure prioritize colour exposure contrast and white balance matching over atmospheric haze the background should remain clear natural and photographic do not introduce additional haze fog mist milky veiling or washed out atmospheric effects colour tonal matching match the original photograph s colour temperature white balance exposure brightness contrast saturation black point midtones highlight rolloff shadow response dynamic range photographic grain overall colour grading the inserted background must share the same overall photographic response as the foreground create a subtle natural transition from foreground architecture vegetation valley hills sea horizon sky nearby landscape may retain slightly more detail and contrast than distant landscape but the difference must remain subtle depth keep the landscape clear use only natural depth perception not a visible haze effect nearby areas should remain crisp and detailed distant hills and the sea may have slightly reduced contrast and microdetail due to normal photographic distance but they must not become hazy foggy milky or washed out do not add atmospheric fog visible haze white veil grey veil milky tones mist excessive blue atmospheric scattering washed out distant hills artificial depth haze uniform atmospheric overlays the distant landscape should remain clearly visible sea the sea must match the original photograph s colour exposure and contrast keep the sea natural clear moderately detailed correctly exposed consistent with the surrounding landscape do not make it overly blue cyan hazy dark hdr like or low contrast valley hills maintain a realistic photographic depth hierarchy without exaggerating atmospheric perspective the valley and hills should gradually become slightly softer with distance but remain visually clear and recognizable do not create obvious haze layers or atmospheric bands sky horizon create a natural transition between the distant landscape sea and sky avoid any visible compositing boundary or abrupt change in colour brightness or exposure the horizon should be clean and natural with minimal atmospheric diffusion important do not invent atmosphere use the original photograph as the absolute reference for atmospheric character do not add haze merely to integrate the background if the original photograph is clear keep the inserted background clear if some atmospheric perspective is naturally present in the original reproduce it very subtly and only to the degree necessary for consistency the background should not become more hazy than the original photograph final result the viewer should perceive one continuous photograph with a naturally integrated background the background must not look pasted in but integration should be achieved primarily through matching colour exposure contrast white balance tonal response rather than through haze absolute requirement minimal atmospheric haze do not add visible fog mist milky veiling or strong atmospheric scattering keep the valley hills and sea clear crisp and naturally photographic while maintaining only subtle distance based softness where physically necessary the final image should look like one colour grading one exposure one white balance one lighting condition one camera one photograph
