Blurry results typically stem from three factors: insufficient inference steps, low guidance scale, or vague prompts. First, increase num_inference_steps to 35-45 for sharper detail. Raise guidance_scale from the default 3 to 5-7 to strengthen prompt adherence. Ensure your input image is high resolution; upscaling a low-res source before transformation yields better results. Add "high detail, sharp focus, 8k, professional photography" to your prompt and "blurry, soft focus, low resolution" to your negative prompt. If issues persist, try adjusting strength—values too close to 1.0 may introduce artifacts. For specialized high-fidelity portrait editing, compare results with
