负面提示词

// 负面提示词库
const NEGATIVE_PROMPTS = {
  quality: [
    "blurry", "low quality", "low resolution", "pixelated",
    "jpeg artifacts", "compression artifacts", "noise",
    "poorly drawn", "bad anatomy", "disfigured"
  ],

  anatomy: [
    "extra fingers", "mutated hands", "extra limbs",
    "missing limbs", "floating limbs", "disconnected limbs",
    "malformed hands", "fused fingers", "too many fingers"
  ],

// 按用例预设的负面提示词
const NEGATIVE_PRESETS = {
  portrait: "bad anatomy, disfigured, mutated, extra limbs, ugly face, blurry, low quality",

迭代式优化

// 提示词迭代工作流
interface PromptIteration {
  version: number;
  prompt: string;
  result: ImageResult;
  adjustments: Adjustment[];
  next: string;
}

// 常见调整策略
const ADJUSTMENT_STRATEGIES = {
  too_busy: "Add 'minimalist', 'clean', 'simple' or use negative 'cluttered'",
  wrong_style: "Be more specific about art style, add artist references",
  bad_composition: "Add specific composition terms, camera angle, framing",
  wrong_mood: "Adjust lighting, color palette, and atmospheric descriptors",
  lack_detail: "Add 'highly detailed', 'intricate', specific texture words",
  too_realistic: "Add illustration/art style keywords, remove photo terms",
  too_artistic: "Add 'photorealistic', 'photo', 'DSLR', remove art terms"
};

工作流模板

单图生成工作流

1. 明确目标：该图像用于什么用途？
2. 主题定义：清晰描述主体内容
3. 风格选择：选定艺术风格与情绪基调
4. 技术参数：添加光照、构图与质量修饰词
5. 平台适配：针对目标生成器进行优化
6. 初始生成：产出第一版图像
7. 迭代优化：依据结果持续精调提示词

批量提示词工作流

1. 模板构建：创建可复用的基础提示词模板
2. 变量定义：识别需动态替换的可变元素
3. 批量生成：批量产出多样化图像
4. 质量筛选：人工审查并过滤结果
5. 提示词优化：按需调整提示词以提升效果

最佳实践

提示词撰写

1. 力求具体，但避免冗长繁复
2. 词序至关重要：关键要素前置
3. 使用业界通用、广泛理解的术语
4. 引用知名艺术家或风格作为参照
5. 务必包含技术质量类修饰词

迭代策略

1. 从简入手，逐步增加复杂度
2. 每次仅调整单一变量
3. 保存已验证有效的提示词
4. 持续积累个人风格词库
5. 深入掌握各平台的能力边界与优势特性
