В нано банане про после внесения 2-3 правок у картинок сильно падает качество(слетает контраст и детализация, генерации становятся блёклыми). Провела много тестов и собрала универсальный промпт, который позволяет вернуть обратно приемлемое качество. Иногда срабатывает со второй попытки(генерю в хиггсфилде). Докручивайте при необходимости. Restore high-frequency spatial detail and true edge acutance. Recover lost fine-detail information across all frequency bands, including micro-textures, sub-pixel surface variation, and high-frequency luminance detail. Reinstate local contrast, micro-contrast, and mid-frequency separation to prevent visual flattening and material blending. Expand effective dynamic range with controlled highlight compression and smooth highlight roll-off. Restore clean shadow detail without crushing or noise amplification. Re-establish physically plausible tone mapping with balanced gamma response and perceptually uniform luminance transitions. Correct tonal gradation and remove banding, posterization, quantization artifacts, and stepped gradients, especially in skies, haze, volumetrics, and soft lighting transitions. Eliminate compression artifacts including macroblocking, mosquito noise, ringing, smearing, chroma subsampling artifacts, and texture collapse. Remove excessive denoising, spatial smoothing, temporal smoothing, and over-aggressive noise reduction that causes plastic or waxy surfaces. Restore natural stochastic texture variation and subtle filmic grain structure without introducing synthetic noise or pattern repetition. Reconstruct accurate color reproduction using a stable wide-gamut color space. Normalize color primaries and white point. Restore clean chroma separation and prevent hue drift, color bleeding, and midtone contamination. Reapply a physically coherent color pipeline with correct color management. Apply a consistent, filmic LUT-based color transform with controlled contrast curve, preserving highlight headroom and shadow depth. Avoid baked-in or destructive LUT clipping. Ensure LUT operates in linear or scene-referred space prior to display-referred conversion. Maintain chromatic consistency across the frame. Ensure proper color space handling (linear → scene-referred → display-referred). Avoid gamma errors, double tone mapping, and incorrect transfer functions. Maintain perceptually smooth transitions across luminance and chroma channels. Restore material response accuracy, including correct diffuse-to-specular energy balance, surface roughness variation, Fresnel behavior, and reflection intensity. Ensure physically consistent global illumination, ambient occlusion continuity, and volumetric light integration. Improve depth perception through coherent shading gradients, stable atmospheric perspective, and accurate light scattering. Maintain clean silhouettes, stable object boundaries, and high-frequency edge integrity without haloing or sharpening artifacts. Preserve original composition, framing, camera perspective, and spatial relationships. Deliver ultra-high-fidelity output with stable detail at all scales, clean gradients, accurate color science, and physically grounded realism. No text, no watermark.
