Model Overview: Analog Imperfection (Instant-Coda-Emulsio)This custom SD 1.5 merge is designed to reproduce the raw, unpolished, and intentionally flawed aesthetic of vintage analog photography. It leans heavily into "analog ugliness"—embracing heavy grain, harsh artifacts, color cast, and realistic optic flaws rather than clean, digital perfection.Important Note: This model is not plug-and-play. It requires an understanding of how lighting prompts and prompt weights interact to drive the style.Core Aesthetic Styles<ul><li>Vivid Style (High Contrast &amp; Sun Flares)</li><li>Faded Style (Muted &amp; Flat)</li></ul>Tips for Best Results<ul><li>Keep Prompts Short for Pure Analog Effects: The model performs best with simple, natural scenes and short prompts.</li><li>Experiment with Weights: Prompt weights are essential to dial in the intensity of film defects.</li><li>Match Lighting to Effects: For realistic results, match your visual effects with the correct light source (e.g., avoid forcing light leaks in overcast scenes, or pair muted tones directly with cloudy lighting).</li><li>Embrace the Artifacts: The model thrives on unpredictable, organic-looking analog flaws—tweak your prompts iteratively to find the sweet spot.</li><li>Handling Human Subjects: When generating people, SD 1.5 tends to automatically "fix" and clean up faces/bodies, which can reduce or eliminate the raw analog style. To counter this digital cleanup bias. Force optical imperfection by adding terms like out of focus, blurry, or motion blur. Frame subjects from behind (e.g., back view) to prioritize the atmospheric environment over facial detail.</li><li>Do NOT Use Upscalers or Face Restorers: Avoid high-res fix, AI upscalers, or detail enhancers. Blur, soft focus, and optical artifacts are the core identity of this model.</li></ul>Prompt Structure: [full view/long view/close-up/camera angle], [your simple promot], [light], [style][light]<ul><li>sunlight, harsh sunlight, harsh directional sunlight, midday sunlight, soft sunlight</li><li>overcast sky, diffused lighting, overcast flat lighting, cloudy day</li></ul>[style]<ul><li>analog photography, (polaroid photography:1.2), (light leak:1.2), (soft focus:1.3) - sunlight.</li><li>analog photography, (polaroid photography:1.2), light leak, (soft focus:1.3) - overcast flat light.</li></ul>negative prompt: flat colors, faded colors, illustration, digital illustration, art, anime, dslr, painting, 3d, cgi, render, perfect lighting - for sunlight.negative prompt: vibrant colors, vivid colors, bold colors, illustration, digital illustration, art, anime, dslr, painting, 3d, cgi, render, perfect lighting - for overcast flat lighting.e.g.,<ul><li>full view, a wild flowers field, harsh directional sunlight, clear sky, strong shadows, vibrant colors, analog photography, (polaroid photography:1.2), (light leak:1.2), (soft focus:1.3).</li><li>close-up a wild flowers field, harsh directional sunlight, clear sky, strong shadows, vibrant colors, lens flare, analog photography, (polaroid photography:1.2), (light leak:1.2), (soft focus:1.3).</li><li>long view, a wild flowers field, soft sunlight, clear sky, soft shadows, vibrant colors, lens flare, analog photography, (polaroid photography:1.2), (light leak:1.2), (soft focus:1.3).</li><li>long view, a wild flowers field, soft sunlight, clear sky, soft shadows, vibrant colors, (lens flare), analog photography, (polaroid photography:1.2), (light leak:1.2), (soft focus:1.3).</li><li>full view, a wild flowers field, overcast sky, diffused lighting, soft shadows, low contrast, faded colors, muted colors, cold tones, analog photography, (polaroid photography:1.2), light leak, (soft focus:1.3).</li></ul><ul><li>prompt lenght: 75tok</li><li>sampler: dpm++sde</li><li>steps: 40</li><li>clip skip: 2 (1-4 experiment)</li><li>old A1111 (better analog look)</li></ul>
