Detailed guide for crafting textual descriptions specifically for SDXL image generation, covering the dual-encoder system, optimal prompt lengths, and style-specific formulas for photorealism, illustration, and concept art.
SDXL Prompt Guide: 1. **Dual Encoder System**: SDXL uses two text encoders (OpenCLIP ViT-bigG and CLIP ViT-L) for richer text understanding 2. **Longer Prompts**: SDXL supports up to 150+ tokens vs 77 for SD 1.5 3. **Natural Language**: Write more descriptively, less keyword-heavy 4. **Style Formulas**: - Photorealism: "photograph of [subject], DSLR, 85mm lens, f/1.8, bokeh, natural lighting" - Illustration: "digital illustration of [subject], trending on artstation, concept art, vibrant colors" - Concept Art: "concept art, [subject], cinematic, dramatic lighting, matte painting" 5. **Refiner Pipeline**: Use base + refiner for maximum quality 6. **Aspect Ratios**: SDXL trained on multiple aspect ratios — specify for best results
